  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

I have just tried with a variety of different sizes and from all of the different ID input options and it worked every time.

Can you try the “By ID” File input instead of link and see if that works?

Have you used google drive before? is it possible you didn’t set up credentials correctly or didn’t set up the right scopes?
