I have multi project pipelines and within my downstream pipeline (e2e) I have defined a chrome job which runs on every push, merge request and nightly scheduled pipeline. I created an almost identical firefox job that I want to run only on the nightly pipeline. The caveat is that upon logging the predefined gitlab variables during the install phase, I saw that the nightly pipeline has CI_PIPELINE_SOURCE = pipeline, instead of scheduled, and this is where all problems arose for me.
