@TWiStErRob I'm trying to use the same workarounds that you had success with but unfortunately I can't get it to work somehow. I'll be very grateful if you could take a pass and offer any suggestions you might have 🙏🏻 https://github.com/airbnb/Showkase/actions/runs/9476982031/job/26110795032?pr=393

Update: Nvm, I forgot to add this line bash --noprofile --norc -eo pipefail "${{ steps.script.outputs.file }}". Thanks for coming up with this workaround!
