(Azure DevOps only) What format is your remote URL?

None

Can you access the remote repository directly in the browser?

Yes, I can access the repository

Expected behavior

There is a Gitlab self-hosted server.

The client uses Git on the command line on Windows.

We clone the repository.

OAuth is used for authentication.

Browser opens.

We approve request.

Cloning works

Actual behavior

It works, but after approving in the browser we receive an error "The string binding is invalid".

However, cloning continues normally.

Can we get rid of the error message as it does not seem to be an error behind?

Start by reproducing the GitLab self-hosted OAuth clone flow on Windows 11 with Git Credential Manager 2.5.1. The payload names no source files or tests, so trace the OAuth completion path and compare the reported binding error with the successful clone; done means the misleading error no longer appears while authentication still succeeds.
