Scheduled and "started" GL pipeline not showing up anywhere

Hi, I have a .gitlab-ci.yml script with a job that is ran only when a certain variable is present. I scheduled a pipeline and added this variable to the schedule. When I (manually) start (“play”) the pipeline, GL says “Successfully scheduled a pipeline to run. Go to the Pipelines page for details.”. However, it is nowhere to be seen (it’s not pending, or aborted etc.). If I run “gitlab-runner exec shell --env my_variable …” locally, it runs fine.
