Summary
Hello,
I’m experiencing an issue with my Fab publisher account and have been unable to upload new assets for over a week.
Migration Issue
I successfully migrated 6 out of 7 Sketchfab models to Fab.
One remaining model has not migrated.
When I click Migrate Listings, the request fails immediately.
Browser Network log:
Request: POST /i/user/migration/start_sf
Status: 500 Internal Server Error
Response: {“detail”:“Internal error”}
Manual Upload Issue
I also cannot upload assets manually.
Uploading either a ZIP or FBX file results in “Unexpected error.”
The issue occurs regardless of the file type.
I have tried multiple browsers with the same result.
What type of bug are you experiencing?
Publishing
Steps to Reproduce
Log in to my Fab publisher account.
Go to Publish.
Click Migrate Listings.
The migration request is sent to /i/user/migration/start_sf.
The request immediately fails with HTTP 500 Internal Server Error.
Create a new listing and try uploading either a ZIP or FBX file.
The upload fails with “Unexpected error.”
Expected Result
Clicking Migrate Listings should import any eligible Sketchfab models that have not yet been migrated.
Creating a new listing should allow ZIP and FBX files to upload successfully without errors.
Observed Result
The migration fails immediately with HTTP 500 Internal Server Error.
The API response is:
{“detail”:“Internal error”}
Manual uploads of both ZIP and FBX files fail with “Unexpected error.”
The issue has persisted for more than one week across multiple attempts.
Platform
Fab website
Google Chrome (latest version)
Operating System
Windows 11 64-bit

Additional Notes
Six of my seven Sketchfab models migrated successfully.
One remaining model has not migrated:
The model is Free, uses the Standard license, and has a ZIP source file.
I have never successfully uploaded a new asset directly to Fab. All existing Fab listings came from Sketchfab migration.
Browser Network tab shows:
POST /i/user/migration/start_sf
HTTP 500 Internal Server Error
Response: {“detail”:“Internal error”}
Please check whether there is an issue with my publisher account or migration state.
