Cannot add only some repos to magit forge

[dit7ya]

So far only for two repos I have encountered a mysterious error that I just cannot troubleshoot (I have tried reinstalling all my emacs config).

When I call M-x forge-add-repository it just returns Invalid base64 data and fails.

Any idea how I might go about debugging it?

I believe I saw a similar report somewhere recently but I didn't take a note. If I remember correctly gitlab was mentioned and that it promises to provide base64 data and then fails to do so.

Any idea how I might go about debugging it?

Start by M-x toggle-debug-on-error and trigger the issue again. Then M-x eval-buffer in the relevant buffers to have less byte-code appear in the backtrace. Rince and repeat and post a useful backtrace.

At this point we should know what kind of object cannot be saved, likely because we assume that the upstream id for that object is base64 encoded when it actually isn't. We should also know where the error is ultimately triggered and you should be able to add a debug statement to print the unexpected value so that we can investigate it.

This is the backtrace

How can I find the relevant buffers to eval?

Fixed with 483baae.
