Layer failing to load in Field Maps, but loads in Collector

[maoneill9]

Hello,

I have a web app that has been in use in Collector for several years with little to no issues. I am working on migrating over to Field Maps, but am having issues getting one of my layers to load. The troubleshooting log gives me the error "Layer failed to load with error: Domain exists". I have another layer that is an exact copy just without some filters, so they have the same domains. I'm not sure why it would be an issue with the domains if the other layer is loading just fine. The feature class also only has 1 layer, not several.

Also the layer that is throwing me the error does load occasionally, so I'm stumped as to why its not working sometimes. Thank you in advance for the help!

Check to make sure you have it marked to use Field Maps in the settings.

If the web map you made was created using an old version of the Map Viewer you may need to open it with the new Map Viewer and resave it.
