Why Gitlab CI docker build tagging problem - gitlab-ci

Question

I have been trying to build my project and deployment to a remote server using gitlab CI runner and using this link as reference
https://www.digitalocean.com/community/tutorials/how-to-set-up-a-continuous-deployment-pipeline-with-gitlab-ci-cd-on-ubuntu-18-04
After runing the pipeline, the publish stage is giving error about the docker tagging
$ docker build -t $TAG_COMMIT -t $TAG_LATEST .
invalid argument "/patch-9:64a25b49" for "-t, --tag" flag: invalid reference format
I have tried changing the docker build tagging in different formats but still could not find out why the error.
I have tried changing the tagging
TAG_LATEST: ${CI_REGISTRY_IMAGE}/${CI_COMMIT_REF_NAME}:latest
TAG_COMMIT:${CI_REGISTRY_IMAGE}/${CI_COMMIT_REF_NAME}:${CI_COMMIT_SHORT_SHA}
but I am still get the error
$ cd $GOPATH/src/$REPO/$NAMESPACE/$PROJECT
$ docker build -t $TAG_COMMIT -t $TAG_LATEST .
invalid argument "/patch-10:fbf4855b" for "-t, --tag" flag: invalid reference format
See 'docker build --help'.
Can anyone help me solve this problem?

I suggest you change your $CI_COMMIT_REF_NAME to $CI_COMMIT_REF_SLUG
Maybe this solved.
