Information on your n8n setup

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

Hi @imkev8888 Welcome!
That is strange, although have you tried getting the file straight from the n8n form? As sometimes i have also seen webhook’s post method not getting the file properly.

I need to use a webhook to listen for new images. This is strange, because the issue only started in the last two days — the workflow was working perfectly before. Now I’ve tested that a binary file can’t be accessed in one workflow, which is very odd. I wonder whether an n8n workspace or server update caused the issue. See the screenshot: the same expression, one run fails and one passes

@imkev8888
So I’d test this first: Set the field to file_0 directly, or use an expression like {{ Object.keys($binary)[0] }}
If the Download button in the execution view still fails even after switching the field to file_0, then I’d start suspecting a Cloud-side issue or a temporary platform regression. But based on the screenshots alone, I would first rule out the field reference, because that part looks incorrect.

it fails from the start, couldnt download file from first node
