Note: I am using Emacs 29.2 on GNU/Linux.  I did not get the same
results as you described and part of the reason might be due to
differing versions of Emacs.

1. The URL you provided does not give access to the file
‘my-repo-pins.el’ within Emacs.  Here is a URL that other readers should
be able to use in order to view your source file:

https://raw.githubusercontent.com/picnoir/my-repo-pins/master/my-repo-pins.el

2. After downloading your source file, I loaded it into Emacs using:

  $ emacs -Q my-repo-pins.el

3. I then byte-compiled the file and loaded it into Emacs using the
‘Emacs-Lisp’ menu entry ‘Byte compile and Load’.  (There were a number
of warnings about the use of single quotes in several functions’
docstrings due to a new syntax requirement, but those can be ignored for
this discussion.)

4. I switched to the *scratch* buffer and evaluated the following
expression using C-x C-e:

   (my-repo-pins--clone-project "test/test")

This caused the debugger to be triggered and a stack trace ("backtrace")
of function calls was generated.  That backtrace is included at the end
of this message in case you or any readers might be able to follow it to
point out some error(s).

Note that I did NOT compile the elisp file natively.  The error was
generated after byte-compiling the file only.  The positive point from
this is that backtrace might be useful for finding the source of the
problem, and eliminating it from the natively-compiled version, too.

5. Backtrace:
