I am not an expert with gitlab si I am seeking help.
I have a git repository and I made the mistake to install a code inside with files bigger than 100 Mo, and I committed several times before pushing to Gitlab. Off course when I pushed, it was not working because of files bigger than 100Mo. I suceed to revert the files from the commits and erase one of the blob but now I have the same error with a blob_ID linked with no path.

and when I am doing :

git ls-tree -r HEAD | grep 394310bc7d1d2eb1f930038862f56d80aa532aaa

nothing happened

I don’t know how to remove this blob from all my previous commits.
Thank you for your help.
