Careful if you implement the n8n backup to Github workflow in Week 4:
If you save your workflows with pinned data, the backup to Github will fail if the text strings in the Base64 node are too long. That happened to me trying to upload the Fathom workflow from week 2 with pinned data, where the long transcripts were preserved over several nodes. Archiving the workflow didn't work, because archived workflows are still retrieved. Just unpin the nodes, save the workflow and run the Github workflow again.
But more importantly: great workflow! Now everything runs smoothly. So thanks, Serop!
