Given that error reporting in "guix pull" is rather basic, maybe try
substituting or building git-minimal outside "guix pull", like this:

$ guix build /gnu/store/6rbibj988j90d8gyccvxrqmkfr0l3mk6-git-minimal-2.36.1.drv

Maybe that will have more information (also easier to attempt to reproduce for
other people)?

Also, I'm wondering if it's case-related somehow, could you run

$ guix build echo
> something like ‘/gnu/store/x2byq2a04pij2m2gqbcy11mqikz07i1m-hello-2.12’
$ /gnu/store/x2byq2a04pij2m2gqbcy11mqikz07i1m-hello-2.12/bin/HELLO # type 
HELLO, not hello!

and tell use the output of that?

Greetings,
Maxime.
