unclear error message when trying to merge a branch from a fork.

Summary

similar to #2051 (closed)

eclipse/aidge/aidge_core!102 (closed)

We ensured that this is not due to lack of empty memory on our group or bc I tried to push a file too big (there are bigger files in the repo).

Steps to reproduce

(I'm can only wonder here)

• Create a branch A on a fork
• get ECA
• Create an MR for branch A on official project
• Try to merge

What is the current bug behavior?

Trying to merge the MR that meets all the requirements raises an error :

An error occurred while merging. Try again.

What is the expected correct behavior?

The merge should proceed normally
