Using ArcPro 2.9 I can Define and Build Overviews using all the default settings successfully (output is TIF overviews), but trying the same in a script using Arcpy with the default ArcPro environment the TIF overviews are consistently blank no matter what I try. That is, the actual TIF files themselves are mostly empty (only a few kilobytes each) and although they are in the mosaic dataset table, they do not draw at all.
Is this a known bug? Even when copying the python output from ArcPro it will not work in a standalone script.

You are using that? T
Definition Query perhaps?
BUG-000103572: Overviews are not generated for a mosaic dataset whe.. (esri.com)
Bug BUG-000103572
Synopsis
Overviews are not generated for a mosaic dataset when running the Build Overviews tool with a definition query in ArcGIS Pro.
Hi Dan, thanks for the reply. There is no definition query.
The command is as follows:
arcpy.DefineOverviews_management(mosaic_dataset, overview_dir)
arcpy.BuildOverviews_management(mosaic_dataset)
Don't know, but this appears in the help topic
You cannot build overviews for a referenced mosaic dataset.
If you think it is a bug, then I would flag it to tech support. At least they can track down why your process is failing.
Hi Dan, thanks for the reply. Not using a reference. I'll look into tech support.
