What is the reason of error on git push?

I cloned remote repo from bitbucket.

i didn't do yet any changes and already have one file as changed:

Your branch is up-to-date with 'origin/master'.
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

        modified:   www/src/app/locale/Test.csv

no changes added to commit (use "git add" and/or "git commit -a")

in fact its a symlink in the repo.

I tried to remove it and push this change then but get this error:

➜  git:(master) git push origin master

I noticed that in the remote repo Test.csv comes with the low registry in the name of file: www/src/app/locale/test.csv

I tried to rename it and push it. The result the same - i cannot push it with the same error.

I tried to use git config option git config --system core.ignorecase false/true

tried to do like here: How do I commit case-sensitive only filename changes in Git?

always result is the same.

Solution

What is the reason of error on git push?

The reason is contained in the response from the server:

remote: One of your commit messages is missing an issue ID:

The remote repo requires that all commit messages must reference a corresponding entry in the bug tracker. Your commit message, however, is simply the word "test".
