Map layer failed to load - error 3079 related to ESRIGNSS field

TanithLives

Hi all. Just wondering if anybody has insight into the 3079 error that returns the description:

"Domain exists. The domain ESRI_FIX_TYPE_DOMAIN already exists but has a conflicting definition. Make sure the fields using the domain have the same field type"

It causes layers to not load in FieldMaps. Weirdly, despite the fact I set up layers in exactly the same way each time, the 3079 error appears random. In my case, I set up three data collection layers: Points, Lines, Areas. Each has high-precision GPS enabled. Each of the layers throws up a problem - usually one or two at a time.

I've worked out that it is the GNSS fields that ESRI itself creates when you tick the GPS metadata box when creating layers. A workaround at the moment seems to be deleting the offending field. 

This isn't ideal and a waste of time. Does anybody have any idea why this ESRI-created field does this - it seems a bit ridiculous. 

Cheers

 

EDIT: I noticed that maps based on an earlier template (Mar 2025) did not have this problem. I think I have narrowed it down to the esrignss_fixtype domain list. Old versions have six values:

New maps/templates with GNSS enabled have five values:

I don't know why, but the new values seems to be causing the issue, as deleting this whole field fixes the domain issue...

Any insights from people smarter than me?

Hi @TanithLives , sorry for the delay in this response as I just came across this post. The coded value "3" for these domains (PrecisePositioningService) is indeed what causes these loading errors in Field Maps. Point layers created after the Sept 2025 release should be fixed and not include this unexpected value. For newly created Line and Polygon layers with GNSS metadata, the fix is coming in the next AGOL update within the next couple of days. 

For any existing layer that is running into this issue, the fix would be to remove the unexpected domain value as you have pointed out.
