Working On An Assignment For School, Encountering 3709 Error

[ConnorBJohnson]

So, I am still fairly new to ArcGIS Online and Field Maps. While trying to make a data dictionary for an assignment, I encountered an issue loading the fields for data entry in Field Maps. 

Initially, the line and polygon features wouldn't load. I refreshed them, restarted the app, restarted my phone, and the results were the same. I checked the error message and it came back with the code 3709: Domain exists but has a conflicting definition. All the error codes provided the same domain name, which was ESRI_FIX_TYPE_DOMAIN. 

I did some digging and it suggested that it was because my domains weren't unique. So after doing some altering, correcting, and adjusting, I saved the line and polygon forms and reopened Field Maps. However, now it was my point features that were not loading even though they were before. I checked and the error code was identical. Any alterations that I made to the point features flipped the non-functional features back to the lines/polygons, and so on. 

At this point, I am at something of a loss because even deleting the map and everything related to it and rebuilding it from scratch has not fixed this issue, nor do any of the forum posts I have seen describe this specific issue. I certainly didn't make any of this prior to October 2019, as the ESRI technical support page suggests. I have been picking away at this for about 6 hours now and I do not have the faintest clue what to do. Any advice would be greatly appreciated.

Hi @ConnorBJohnson 

Sometimes the errors can be pointers to symptoms and not the actual cause.

The domain you mention is related to the fields added to a layer to log all GPS data such as position source, accuracy, etc. 
In this case the domain is used by the ESRIGNSS_WORST_FIXTYPE  field for lines & polygons, and ESRIGNSS_FIXTYPE for points.

To troubleshoot, and if the layer itself doesn't contain anything important, you can delete the ESRIGNSS_  fields and try again.  
You will have to do that from the layer's Details > Data > Fields page.

This docs page describes the various fields added when you run the "Add GPS Metadata Fields" tool in ArcGIS Pro.  https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/add-gps-metadata-fields.htm

When you create a new hosted feature class in AGOL you will see this option:

If you don't have to record all the GNSS metadata, try to create your layers without the setting turned on.
