Hi - we have a stand-alone ArcGIS Server (v11.5) that we are hosting for a customer to enable them to do custom prints from ArcGIS Online apps. The print service is set as synchronous (required for printing from Web App Builder apps) and secured with user credentials and these are embedded within an item in the customer's ArcGIS Online account and the item is then shared and used across ArcGIS Online (e.g. in the print widgets etc). This approach has been in place and working fine for a couple of years.  For information - we cannot currently change the print service to asynchronous, because this mode is not supported by older apps (e.g. Web App Builder) that the customer is still using.  Recently the customer has started experiencing failed prints due to intermittent 504 gateway timeouts. We have investigated and found that there are no timeouts happening on the ArcGIS Server (the timeouts are set quite long and the load is minimal) and when a print fails, there are no errors in ArcGIS Server and the output has been generated in the output directory.  We have tested printing directly using the ArcGIS Server URL (user needs to enter credentials each time) and this consistently works without errors. However, we can't use this in production. Our investigation suggests the timeout is coming from the utility.arcgis.com proxy that is used when using an item with embedded credentials: The error in the browser also states "Error from CloudFront". CloudFront is not part of our infrastructure, so this error must therefore surely be coming from the utility service proxy.  Further testing has revealed that successul prints tend to complete in <30s, whereas failed prints tend to fail around the 30s mark. I personally believe this indicates there is a timeout setting (possibly 30s) somewhere in the utility.arcgis.com proxy, probably in CloudFront. This would explain why longer prints would fail but there are no errors in ArcGIS Server, because the proxy is timing out before the request is completed in ArcGIS Server. We have raised a support call but are not getting very far. Can anyone confirm if there is indeed a timeout setting for the utility service proxy if so, what it is set to? ... View more

I am trying to create a report that will ultimately be published as a reporting service in ArcGIS Server. Our customer has asked that the report includes an appendix showing the attachments (photos) for any features in the report.  I have created a details report to do this with a feature reference (from an attribute) and an attachment frame that is set as a 2x2 grid (ideally we would like this to auto expand based on how many photos there are, but that's a separate issue). This is working to a degree, but is producing a page (or record) for every feature, regardless of whether there are any attachments. So if there are 10 features and only 2 of them have attachments, it's generating a 10 page report with mostly empty pages, which is not good! I thought perhaps I could filter the report, but this seems to require a SQL expression (cannot use arcade) which would require a field containing the attachment count (or a flag). I also tried adding an Expression to the report to provide this attachment count - e.g. Count(Attachments($feature)). However, this produces an error along the lines of "Function is not supported in current profile".  Showing attachments only when the exist seems like a common thing to want to do, given that not all features are necessarily going to have attachments.  Is there a way to achieve this or workaround that doesn't involve adding an attachment count field to the feature layer?  I don't think our customer will accept a report that includes multiple empty pages.  ...

I'm trying to re-create the functionality of the Screening widget from Web App Builder within Experience Builder. This involves using the Near Me widget and Print widget with a custom print service. I have been trying to follow the steps in the blog here https://www.esri.com/arcgis-blog/products/experience-builder/sustainable-development/recreating-the-...  and also this one about puiblishing a custom print service for reporting here https://www.esri.com/arcgis-blog/products/arcgis-enterprise/national-government/creating-a-custom-pr... Amongst other things, one key capability is for the user to be able to add a custom title to the report, for example the name of the site they have generated the report for. With map layouts published to a print service you can add custom parameters using braces, for example {sub-title}. When published they will be presented as parameters in the print service for users to complete. I was hoping that publishing a reporting service would be similar. However, I've tried adding a text box as a custom parameter {report-subtitle} and whilst this publishes ok (provided the text box has some text in it, it fails if the text box is empty), when I come to configure the print widget in Experience Builder, the report template is not listed. If I remove the custom parameter and re-publish, the report template is listed in the print widget configuration. Are custom parameters supported in the reporting service and the Experience Builder print widget?  If not, is there another way for the user to be able to add a title of their own to the report? ...

We have been trying to create a replacement for the Screening widget in Web App Builder within Experience Builder in ArcGIS Online. This involves using the Near Me widget and Print widget with a custom print service (hosted in Server/Enterprise). I followed the steps in the blog here https://www.esri.com/arcgis-blog/products/experience-builder/sustainable-development/recreating-the-...  and also this one about publishing a custom print service for reporting here https://www.esri.com/arcgis-blog/products/arcgis-enterprise/national-government/creating-a-custom-pr... What I would like to acheive is a multi-page report with one page per feature, each containing some attributes and a map showing the location of the feature. I configured a report in Pro using the "Page per feature" template and have added a map element to the "Details" section of the page. However, it seems this is not currently supported as when printing, the individual maps are blank. It is a fairly common requirement to generate a report for a selection of features with the output as a paged report containing a map of the feature location and it's attributes on each page.  This is clearly supported in ArcGIS Pro as the ability to add maps to the "details" section of a paged report exists. However, this does not appear to be supported when published to server/enterprise. Having the ability to only have one map per report really restricts the usefulness of this capability and what we can do with reporting in Experience Builder. ... View more

I'm trying to re-create the functionality of the Screening widget from Web App Builder within Experience Builder. This involves using the Near Me widget and Print widget with a custom print service. I have been trying to follow the steps in the blog here https://www.esri.com/arcgis-blog/products/experience-builder/sustainable-development/recreating-the-screening-widget-workflow/  and also this one about puiblishing a custom print service for reporting here https://www.esri.com/arcgis-blog/products/arcgis-enterprise/national-government/creating-a-custom-print-service-with-reporting-capability/ What I would like to acheive is a multi-page report with one page per feature, each containing some attributes and a map showing the location of the feature. I've configured a report in Pro using the "Page per feature" template and have added a map element to the "Details" section of the page. However, I have two issues:  1) I assumed this map frame needed to be set with "None" for the map as will be populated with the web map from the print service request (as happens for standard print templates). However, when I publish this and try to print, it only prints the details and a blank map. How do I get it to pick up the web map or do I need to set the map in pro before publishing (that's different to how the standard print service works)? 2) When following this workflow, it suggests copying across standard print templates into the folder before publishing, but I don't want users to be able to select standard print templates, just the reporting ones I've configured. The print widget in experience builder also seems to want me to specify a map template, in addition to the report template. I'm not sure I need a separate map and would prefer just a paged report showing map and details for each feature. Is it possible not to have a map, or do I need to select a map template for it to work? If anyone else has set up something similar (i.e. a paged report per feature with maps on each page) and successfully got this working with the Near Me/Print widget combo in Experience Builder, then any tips, thoughts or pointers in the right direction would be much appreciated.

We have a customer that is using an external ArcGIS Server (v11.1) print service (that we manage) in ArcGIS Online. This is added as a geoprocessing service with embedded credentials and has ben working fine for 18 months plus. This morning (Mon 3rd Feb 2025) they are getting errors using the print service in their apps. I have checked the ArcGIS Server and it's up and the print service is responding ok. If I use the external URL of the print service directly (not the item with embedded credentials) then printing from an app works (after entering credentials), which proves the print service is not the issue. I've also tried to create a new GP service item using the URL, which creates ok. However, when I try to add the resulting item URL (starting with utility.arcgis.com) to an app, then it fails. It also fails if I choose to select this as the default utility service for the organisation. This all leads me to think that it's an issue with the ArcGIS utility service/proxy (utility.arcgis.com). I have raised with Esri support, but I'd be interested to know if others are experiencing the same issues with services that have embedded credentials (i.e. using utility.arcgis.com). ... View more

I have a large dataset that I may want to publish as a hosted layer in ArcGIS Online. The source file geodatabase containing the single source feature class is approx 5 GB in size. However, when I published this as a hosted feature layer (from ArcGIS Pro 3.3.1), the resulting size of the feature layer was reported as approx 21 GB. Note that this is a basic read-only feature layer with no sync, no editor tracking and no attachments, so I am trying to understand why the resulting feature layer is so much bigger than the source FGDB. Obviously there is a huge difference in storage credit consumption between 5 GB (approx 1200 credits) and 21 GB (approx 5000 credits). Can anyone explain why the published feature layer is 4x larger than the FGDB? Has anyone else experienced similar? I would expect some difference due to different storage formats, but not 4x difference! ... View more
