Gitlab CI configuration is invalid for conditional statement

Question

Why is this line in my gitlab CI configuration invalid? did not find expected alphabetic or numeric character while scanning an anchor

script:
  - [ ! -z $(docker images -q $IMAGE1) ] && docker tag $IMAGE1 $IMAGE2

How should I modify this line?

I need to check if the image exists before creating a tag for that image. If it doesn't exists, this line should be skipped, but the CI should go on...

You need to quote the command:

script:
  - "[ ! -z $(docker images -q $IMAGE1) ] && docker tag $IMAGE1 $IMAGE2"
