Failed to fetch model packs:

Error message

Failed to fetch model packs: 

What it means

HTTP 500 error body sent by ListModelPacksHandler when db.ListModelPacks fails to load the model packs for the authenticated user's org from the database. It indicates a server-side storage/query failure (not a client problem) — the handler has already passed authentication and minimum client version checks, and the raw database error string is appended to the response.
