TLDR:

When trying to authenticate to a codeberg.org repository while the Web-UI says Authenticated! Close this tab and head back to your terminal the terminal fails with:

rust
Error: api error: failed PKCE code challenge

Location:
    <path>/src/auth.rs:254:20

Steps taken before this behavior occurred:

  1. Wanted to create a release for a preexisting tag
  2. After calling fj release create -b -t<tag> notice that the editor is nvim (aka the $EDITOR variable)
  3. Cancel, since I prefere to use my visual editor (zed, in this case)
  4. Play around trying to fix that (unimportant)
  5. Retry the command
  6. Errors with smf like auth token already used
  7. Logout (fj auth logout)
  8. Try to log back in
  9. The above described happens

Version

fj v0.4.0 installed via cargo install forgejo-cli

I suspect this is caused by forgejo/forgejo!11513, as that fixed S256 PKCE, which is the method forgejo-cli uses. It's likely this shouldn't have ever worked in the first place!

The fix for this should be published in a point release (v0.4.1)

So if I understand correctly this means that the auth part of forgejo-cli needs to be rewritten and validate the challenges?

Rewritten is maybe putting it strongly, but yes, that's what needs fixed.
