Given I have the following variable in my Github repository

MYVAR: My Var

Then I have this part that is executed in Github Actions:

if then... // conditionally setting some variables

MYVAR = ${{vars.MYVAR}}

docker run 
-d 
-e MYVAR=$MYVAR  // error triggered here
ghcr.io/xxx/xxx/:${{github.sha}}-${{github.ref_name}}

But I get the following error during workflow run:

err: bash: line 3: Test: command not found

An odd thing:

If using github secrets I can simply escape the space character

My Var
and then docker won’t complain.
