I'm receiving the below error message in my GitLab pipeline when attempting to create a docker image and then push it up to my docker hub account. It seems to be a syntax issue and I have tried a few combinations but cannot get it to work.
Can anybody help? Thanks.

If you do this, this should solve the issue.
