I'm attempting to create a new hosted Service Layer, from a FileGDB, on ArcGIS Portal, using the publication tools inside of ArcGIS Pro.
I have done this successfully before with other data. This morning however, when attempting to create a new Hosted layer, it fails.
Using the standard "Share as Web Layer" tools in ArcGIS Pro, I configure a Feature layer type and share with everyone in organisation. None of this is new.
However this time, I am getting a generic error message "Failed to Publish Web layer" inside of ArcGIS Pro. When attempting to create the service layer from the ArcGIS Portal admin page, the process just hangs.
"Failed to Publish Web Layer" message is not very helpful at all and there are no further details in the application, so I'm just looking for some starting points to help narrow down the investigation. At this stage I've only found this article, which doesn't help unfortunately.
