Creating MMPK to enterprise or local files fails

[ScottHiggins_PVGIS]

Hi all,

I am trying to package up as a MMPK some hosted layers. I have tried this layers, which originate from a postGres instance but are hosted reference layers.

...\Documents\ArcGIS\GN01_mobile.mmpk 27 MobileMapPackage 2025-08-29 15:30:16 Status: Failed ErrorMessage: An unexpected error has occurred when creating the package. Check your settings and try again.

Is the error in the log, which is generic, and is the same whether exporting the MMPK local or sharing it into Enterprise.

The settings in the Sharing> Map package are all good, and are the same as I have used in AGOL previously without issue.

Has anyone come across this previously?

Any issues I've ever had have been with the data being corrupted or incomplete in some way after an automated scheduled copy process.  The more obvious ones have been missing layers from the .mapx

I don't think there's any functional difference in sharing it into AGOL as it's just creating the MMPK in scratch/temp locally then sharing to AGOL (is my understanding).
