UrlUpdater action causing strange error/warning

[hohwille]

I looked into the logs of the URL Updater github action and found this:

Run cd ide-urls
  cd ide-urls
  git config --global user.name ***
  git config --global user.email ***
  if [ "$(git status -z)" = "" ]
  then
    echo "No changes, nothing to commit."
  else
    git add .
    git commit -m "Update urls"
    git push
  fi
  shell: /usr/bin/bash -e {0}
  env:
    JAVA_HOME: /opt/hostedtoolcache/Java_Temurin-Hotspot_jdk/17.0.14-7/x64
    JAVA_HOME_17_X64: /opt/hostedtoolcache/Java_Temurin-Hotspot_jdk/17.0.14-7/x64
/home/runner/work/_temp/e5b35c3c-db99-478e-b5c6-35164fc9a7c9.sh: line 4: warning: command substitution: ignored null byte in input
[master ea3bbf01] Update urls

Can someone explain what is wrong here?

/home/runner/work/_temp/e5b35c3c-db99-478e-b5c6-35164fc9a7c9.sh: line 4: warning: command substitution: ignored null byte in input

So is line 4 this one?

  if [ "$(git status -z)" = "" ]

So we cannot evaluate $(git status -z) what should actually run the command git status -z and evaluate to the standard output of that command. So it seems that this git command is echoing null bytes causing this warning.
Maybe there is nothing we need to do about it but we could at least leave a comment once we understood what is happening here, if we thing this is intended.
