I'm trying to overwrite a web layer in AGOL from Pro, something I've done many times before but now I've hit a wall. I get the "failed to publish web layer" error and I have no idea why.
StatusMessage: Staging successful
StatusMessage: Uploading service definition
StatusMessage: Publishing tool initialized
StatusMessage: Publishing web layer (AGO)
StatusMessage: Publishing web layer failed (AGO)
StatusMessage: Publishing tool execution failed
ErrorMessage: Failed to publish web layer
Everything is exactly the same as the last time I did this except I'm using 3.0 instead of 2.8. All the field names line up, and this is a layer I've created in Pro.
