### Problem During the migration in https://gitlab.com/gitlab-org/gitlab/-/issues/423445, we discovered a case when one of customers used a regex with `1376` characters: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/130394#note_1538049553. To unblock the migration, we temporary increased the length limit for `commit_message_negative_regex` to 2047 characters. ### Proposal * Contact the customer and reduce the value to fit in 511 characters limit. * Reduce the limit for `commit_message_negative_regex` to 511 characters
