Resolve the Missing Change-Id in Commit Message Footer Error in Git
While working with Git and Gerrit, you might sometimes encounter the error message: "missing Change-Id in commit message footer." This error typically occurs when submitting changes to a Gerrit review system, which requires a unique Change-Id for every commit. This Change-Id helps Gerrit track and manage multiple versions of a patch series.
Here's how you can resolve this issue:
Step-by-Step Resolution
Check for Change-Id in Commit Message:
First, ensure your commit message already contains a Change-Id. You can view the commit message by running:
