Problem downloading offline area in new Collector, but not Collector Classic

Katie_Clark — Thu, 21 Feb 2019 14:44:30 GMT

Hello,

I created a web map which has an editable feature layer in it for our staff to use for offline data collection in the field. On multiple devices, we have been able to successfully download an offline map area in Collector Classic, but not the new Collector app. Since it seems this isn’t an issue with the map being offline capable, any other ideas why this might be happening? I did not receive any other error message other than a generic “download failed”.

Thanks!

Edit/Update: I have received a lot of helpful insight on this topic, and in my particular case, I believe the error was caused by having a copied layer in the web map. I was able to determine this by using the Developer Logging feature described below.

If this issue pertains to you, you can up-vote this idea: https://community.esri.com/ideas/16311-enableallow-maps-with-multiple-copies-of-a-layer-to-be-used-offline-in-collector

Here is a related Geonet blog post that I did not find in my initial research: https://community.esri.com/thread/227015-webmap-can-download-in-collector-classic-but-not-in-new-collector-for-arcgis

Hope this helps someone!

This looks to be an issue with Collector and not ArcGIS Online. I would post this in the Collector forum linked here: https://community.esri.com/community/gis/applications/collector-for-arcgis

Thanks, Russell. I moved it to the Collector forum.

Kylie Donia‌ Hello, I still have not heard any thoughts on this issue, and I was wondering if you could help? You seem to be very knowledgeable about Collector based on other threads I've seen. Or if there is someone else who you think could help could you direct me to them?

Thank you so much!

I also have this problem. I am using an old iPad Air. I can download an off-line map in Classic and all layers work fine but the same map fails to download in the new Collector app. Any help in understanding what is going on would be appreciated.

I am having the same issue with one of our maps

Do you have a Copy of a layer in your Web Map? This will cause the download to fail in Collector. See the following thread:

UPDATE: Cannot create offline area if Webmap has a copy of a layer in new Collector for ArcGIS

Otherwise I suggest logging a case with Support so we can this issue triaged more effectively.

Colin,

Peter,

The map isn't loading for me. Can you share the Map and Feature Layer(s) to a Group and invite the user "Collector4arcgis". I can take a look that way.

Multiple maps now...

While we have encouraged our field users to familiarize themselves with the new Collector app, we have also strongly suggested that they keep both versions of Collector on their devices, since issues like this seem to be unpredictable and not even always reproducable on other devices.

Definitely a bit frustrating, but I guess there are still just a few kinks to work out with the new software? I still haven't been able to figure out exactly why the map didn't download in new Collector.

Peter,

I took a look at your map and reproduced the download error. For your reference and others in this thread, logging can be enabled in the new Collector:

Open the settings > tap your login name at the top 3 times > "Developer" options should appear at the bottom of the settings > Open the Developer options and turn on logging > reproduce the download failure > back in the Developer options, click Logs > you will see more detailed errors that you can review or share out via email, etc.

In Peter's map, and error is being thrown on the "harvest_lines" layer, "The item to be created already exists in the database". This error sounds a lot like a known issue regarding duplicate domain names. I'm guessing you have similar domains applied across the points and lines layers. A simple test would be to remove one of these layers and confirm you can download the map area. If that works, the next step is to investigate the domains. Were they created in ArcGIS online (AGOL) using the list functionality or in Desktop? If you created them in AGOL it applies the field name to the domain name, ie if your field name is "status" the name would be status_domain. If you have another layer with the same field name and you create a domain list for that as well the domain names will be duplicated. When downloaded they are packaged into the same database and the duplicate domains will cause an error. A fix was already applied to AGOL for this but for existing data the lists will need to be modified so they can be renamed with the new scheme, which avoids the potential for duplicates. You can simply open the lists, apply a space to one of the values, remove the space, then save. The new domain name should be applied.

For others, see if you can capture a more specific error using logging and we can look into it. Thanks

Colin

Colin,

Thank you so much for the detailed response, that is extremely useful to know exactly what goes on with the layers.

Unfortunately, I can't seem to open the "Developer" options using the steps you described. I'm probably just missing something obvious...would you be able to provide a screenshot? I am an administrator so I wouldn't think it would be limited by my user type. I am using version 19.0.1, Build 2609.

Again, thank you!!

Katherine,

Here is a screenshot, ensure you are tapping on your login name 3 times rapidly. There should be no dependencies on user type or login.

Hello Colin Lawrence‌, Who should i send the error log to?

Colin, not sure what I did differently (maybe just faster taps?) but it did work this time! I will definitely be using this feature in the future to help with troubleshooting.

ColinLawrence — Tue, 02 Apr 2019 19:05:39 GMT

You can either post it here or send it to me in a direct message. These are also useful to provide to Support when you log a case with them, which depending on if its a known issue, I may have you do.

Colin,

Thanks for your help.

I take it you are recommending creating lists in ArcGIS On-Line.

Would the layers publish better if done from ArcGIS Pro?

I haven’t used AGOL to create lists but it seems like a lot of extra typing and you can’t seem to create lists dependent on another field but if done in desktop – the intuitive lists appear in Collector.

The harvest_lines and harvest_points layers were created in Desktop and published to ArcGIS On-Line. They do have the same domains for a few of the fields.

Operation Status is one of the fields that is duplicated in both – it is named differently in each layer (one is OP_Status – other in Status) but used the same domain in Desktop.

I was using 10.4.something most likely when I first created these layers.

harvest_lines was first published on 11 April 2017 - harvest_points was first published a couple of months earlier on 13 Feb 2017.

Peter,

I wouldnt say i'm recommending that practice; I was more assuming that this is what you used because its easier to run into this issue that way. Creating domains (and curating your data in general) will always be more powerful in Desktop. I would say the online interface is most useful for applying domains to layers created from templates in AGOL or quickly adding a new value to an domain.

In regards to this error, things get a little more murky when your data is coming from Desktop, or at least harder to explain. If i'm remembering correctly, the two source layers would come from separate geodatabases and contain a domain with the same name (different geodatabase, different domain, same name). In this scenario all of the layers were published to the same service, but I see you have a service for each layer. It may be worth trying to republish this data (both harvest layers) as a single service as it sounds like they are indeed coming from the same geodatabase so you shouldn't have the issue noted above. Again your situation is less clear to me so I cannot say with certainty this will work. If it doesn't I would suggest logging a ticket with Support so it can be dug into further.
