Git pre-commit hook "No error" error message

Question

I have a pre-commit hook that when I run returns this error:

error: cannot spawn .git/hooks/pre-commit: No error

I have a #!/bin/sh at the top and have definitely used chmod +x on it. However, those appear to be fixes for when there is a no such file or directory error. My error simply says No error and I cannot work out why.

Code in the hook:

#!/bin/sh

changes() {
  git diff --name-only --diff-filter=AMDR --cached @~..@
}

if changes | grep -q dirname {
  echo "Test"
}

Check first, as in here, if your script does have a final newline.
Its absence would trigger a "no error" message.

Check also the eol style (end of line): LF is prefered for those bash script.

The OP compsciman confirms in the comments that switching to Git For Windows 2.26 from 2.21 solved the issue.

The only recent modification to pre-commit involves the removal of git config --bool option (commit 81e3db4) that I mentioned in "How to color the Git console?".
