Event Editor: No linear referencing service error

MichaelNigbor1 — Tue, 22 Sep 2020 14:58:05 GMT

I'm unable to build a working Event Editor application. After logging in, I'm getting the following error:

I'm attempting to follow the sparse and possibly outdated instructions here. Clearly, I've missed something important in the configuration and I'm looking for ideas.

The error seems to be saying that the app was unable to find an LRS network to work with. I've confirmed that the service it's configured to use has an LRS network that I can manipulate with ArcGIS Pro.

I've created and published a map that includes the LRS Engineering Network along with it's related features, including Redline. I confirmed that M and Z are disabled in the Redline. Feature editing is enabled.

Fortunately, the server I'm using had a pre-installed Event Editor application because I was unable to find the download using the instructions Event Editor Deployment Guide. I could not find an Event Editor listed in My Organization -> Downloads.

I'm attaching the config.json file. Here's how I filled in the values mentioned in the config guide:

webmap: Set to the ID of the map web map created and published for event editing, obtained from the Portal
portalAppID: Set the the ID for the Event Server application registered with the Portal
portalURL: Set to the ArcGIS portal on the same server
geometryServiceUrl: Set to a local geometry server
allowReconcileAndPost: true
allowChangeVersions: true
allowCreateVersions: true
allowDeleteVersions: true

The login works file, which I think means the portalAppID and portalURL are OK. I think the issue must be with the services in the published webmap.

I've checked repeatedly, the map has an LRS network:

I'm attaching the config.json file, in case someone can see the mistake.

Michael Nigbor An area to verify is if Linear Referencing capability is enabled per documentation in link below.

Confirmed. It's enabled.

Do you need to restart the Event Editor when you make changes to config.json?

After making changes to config.json, admin should delete cache and reload the Event Editor web app.

I recycled the application pool, which should clear the cache and reload the web application and will do this whenever I make a change to config.json going forward.

Unfortunately, that didn't change anything. I'm still getting the same error.

Does the Event Editor write a log file anywhere? If so, maybe it will hold some clues

I appreciate the quick response. Thanks.

Michael Nigbor‌ Another point to verify: when creating the webmap for Event Editor - the Map Service should be added not the Feature Service. This is a common misstep and causes confusion.

Re: Event Editor: No linear referencing service error

MichaelNigbor1 — Tue, 22 Sep 2020 20:26:43 GMT

That was the trick! I used the feature service, instead of the map service. Now my Event Editor is working.

Is there any way you can bold the "map service" or add a caution note on the Authoring a web map for Event Viewer page?

Whenever there is editing, I automatically assume feature services should be used. Using the map service for an editing application seems counter-intuitive.

Thanks Ayan Palit for the quick and accurate answer.

I am having this issue but I have gone down the checklist and when I publish the services with location Refencing and Versioning check the published service does not recognize the LRS. All the layers are listed as nonLRS Layers. From the attachments you can see the service has no LRS.

Hi @DuaneWhistle_SSCGP , we're having the identical issue (publishing a service with an LRS, LRS is shown and enabled in the service, but all the layers end up in 'NonLRS' list so it's functionally useless). Did you work out the issue?

Re: Event Editor: No linear referencing service error

DuaneWhistle — Tue, 20 Jul 2021 12:58:37 GMT

Yes, we are on ArcGIS Enterprise 10.7.1 so we had to revert back to ArcGIS Pro 2.5.2 then everything feel into place.

thanks heaps - that’s our setup (10.7.1 and trying with pro 2.8). Will revert to 2.5 and have a go. Hugely appreciated.

Maintaining the version compatibility is an important step and will help streamline the configuration process. ArcGIS Pro, ArcGIS Enterprise and the corresponding Event Edit Web App versions must be in sync. A compatibility matrix can be found at ArcGIS Pipeline Referencing - Useful Resources

I have the same deployment: ArcGIS Enterprise 10.7.1 and ArcGIS Pro 2.8. I am going to revert to 2.5 to test it!
