Hi @layfield_8963,
I'm having trouble recreating this error. I just stood up a clean install of ProGet 2025.7, created an asset directory, and uploaded a file to it. I then ran the command you sent and this is what I see:
pgutil.exe assets metadata set custom --path=test.txt --feed=test-import-data --key=test123 --value=12345
Setting test123 = 12345 on test.txt...
Metadata set.
Can you please navigate to Administration -> Software Info and copy and paste the contents of that here? If you feel more comfortable, you can email it to support@inedo.com with the subject [QA-2790] Database Information. If you email it, please let us know when you do so we can look for it in that mailbox. The only thing I can think of is that your database schema did not update properly on upgrade.
Thanks,
Rich
