ArcGIS Pro 3.2.1:
I have a model that uses the Create Unregistered Table geoprocessing tool. If I accidentally use the model on a file geodatabase, instead of a mobile or enterprise geodatabase, then I get this error:
ERROR 999999: Something unexpected caused the tool to fail. Contact Esri Technical Support (http://esriurl.com/support) to Report a Bug, and refer to the error help for potential solutions or workarounds.
Getting an error is expected in that scenario; the docs and tool description in Pro say the tool is intended for mobile and enterprise geodatabases (implying that file geodatabases are not supported). However, when using the tool in a model (or Python script), the vague error messaging above is not very helpful; it doesn't tell us what the root cause of the problem is.
Could more specific error messaging be added to the tool when it's used on incorrect data types?
Also, could the docs be improved so that they explicitly state that the tool does not support file geodatabases (instead of implying it by omission)? New users might not be aware that it's impossible to create unregistered standalone tables in FGDBs (except when using the File Geodatabase API).
