Invalid option "app"

[brunoparga]

Hi! I run dpl on a GitLab CI/CD pipeline. On December 2, while I was working on tests and really not paying attention to prod, the job started failing for seemingly no reason. It went from:

[...]
$ dpl --provider=heroku --app=$HEROKU_APP --api-key=$HEROKU_API_KEY
Installing deploy dependencies
[...]
Successfully installed dpl-heroku-1.10.16
6 gems installed
[...]

to:

[...]
$ dpl --provider=heroku --app=$HEROKU_APP --api-key=$HEROKU_API_KEY
invalid option "--app="
Cleaning up file based variables
ERROR: Job failed: exit code 1

I can provide more complete logs if needed, but I diffed them and the only differences are things like commit hashes and download times. There seems to be no difference in how dpl actually runs, except for the lines above - especially, no difference with versions of anything (which would show in the diff). My own commit doesn't touch anything related to this, it's an ExpressJS project where a test file is added and one line changes in production code related to seeding the DB.

I can tell that neither of the Heroku-related variables in question changed, at that time or otherwise, on either Heroku or GitLab.

How would I get this job working again?
