Gerrit error when Change-Id in commit messages are missing

Check if your commits have

Change-Id: ...

in their descriptions. Every commit should have them.
you can "git log" to review your commits have

Change-Id

If no, use

git rebase -i

to reword the commit messages and add proper Change-Ids (usually this is a SHA1 of the first version of the reviewed commit).
For the future, you should install commit hook, which automatically adds the required Change-Id.
Execute

scp -p -P 29418 username@your_gerrit_address:hooks/commit-msg .git/hooks/
