Summary

This problem didn’t start after update 38.00, but began last night for me.

Every time I try to send changes to the URC, I consistently get the same error :
Failed to create branch main-6653137745d055b458262e84823e888c on remote: Request failed: status: ‘Client specified an invalid argument’, self: “Branch already exists”, metadata: {“date”: “Sat, 01 Nov 2025 20:14:24 GMT”, “content-type”: “application/grpc”, “content-length”: “0”}

Observed Result

Failed to create branch main-6653137745d055b458262e84823e888c on remote: Request failed: status: ‘Client specified an invalid argument’, self: “Branch already exists”, metadata: {“date”: “Sat, 01 Nov 2025 20:14:24 GMT”, “content-type”: “application/grpc”, “content-length”: “0”}

To work around the problem:
Copy all the files from your map’s Content folder to a separate folder on your computer.
Undo any local changes you made in the UEFN.
Close UEFN and replace the previous Content files in their original location.
Restart UEFN; sending the changes should no longer trigger the error message.
