Update - this issue is tracked in https://gitlab.com/gitlab-org/gitlab/-/issues/438723 and https://gitlab.com/gitlab-org/gitlab/-/issues/434826 ### Problem With the introduction of expand_vars users should be able to use variable + input anywhere, however this does not support any key that is not string, when you try to add `parallel:` (number) or `allow_failure:` (boolean) I am receiving the following error  When I try to force the type using `type: boolean/number` I receive a different error  Its important to note that I did not saw this problem on keys that are type of string (`changes:` or `when:`)
