Code: 3079 Domain already exists

[MindyBurkett]

When I add a new value to a domain for a hosted feature layer then Field Maps errors with the error Domain already exists and the code 3079. Collector does not get this error.

The layer was originally uploaded from an Enterprise Geodatabase in ArcGIS Pro. I am able to modify existing domains using ArcGIS Online. I am not able to add new domains in ArcGIS Online because the button to do so does not appear. I cannot modify the domains of the Hosted feature service in ArcGIS Pro because it gives the warning "The domains for this workspace are read-only".

Hello Mindy

were you able to solve your problem with tech support?  I am experiencing the same type of issue, with a map service and web map that has been working for years... I do have an open ticket with Support as well but I am curious has how other users solve this issue.

Thanks!

Hello 

I believed I solved my problem related to the error 3079 Domain already exists. In my feature class, I had a Domain with a special character in the name (Yes/No as name).... I renamed to Yes_No , all my fields using that domain got updated, I refreshed my map service and I was able to load my web map in Collector and Field maps without issues.

Good luck!

Do you know if a "." is considered a special character? I am running into a similar issue trying to deploy a new Field Map with revisions to our current schema design.

If you've got any hosted feature layer views (HFLV) and made schema changes to domain values, I found I was getting this error in Field Maps. I'd edited some of the HFLV fields to be non-editable so they were no longer inheriting field and domain settings from the Hosted Feature Layer. This meant the HFLV was holding Domain values that were no longer valid and it was throwing this error. Unfortunately the message isn't very logical in this instance as it's actually the domain value NOT existing that is the issue.

If this is the case after making the schema update to the HFL, click the Data tab on the HFLV, click the Fields option, find the applicable field and click the 'Reset to source' option which then refreshes the domain values from the source feature layer.

I can confirm "." seems to cause the issue also.

Hello,

I was getting this error after adding options to a list. Can confirm the '/' was causing the layer to error. I removed and all worked fine again. 

Thanks for the hot tip!

Later post. If somebody stumbles on this and is looking for the solution, go to this post on Esri Support website: Error: 3079: "Domain Exists" in ArcGIS Field Maps

How I solved it:

I noticed that I have three fields where one domain is applied to all three of them. Since I already have the service published I changed the field values for each of those three fields so it created different domains for each field.

After that, the layer was loading without the issue.
