Thanks for catching the issues in Elixir and Gleam. I have also corrected the bug for the Erlang commit and added it here, unless you prefer a specific PR for the Erlang broken test.

I have fixup (squash) some commits together and re-add the forgotten signed-off-by.
Also, I finally run tests locally, so this is the good final commit.
