Workflow can't be activated


I’ve been getting the following error message in a couple of my Workflows:

Workflow could not be activated:

Bad request - please check your parameters

If I execute the workflow manually it works without an issue. This Workflow has been used for about 8 months without any changes and it suddenly stopped working.
Any guesses on how I could start determining on which node the issue could be at?


Information on your n8n setup

n8n version: 0.212.1

It looks like your topic is missing some important information. Could you provide the following if applicable.

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

I literally duplicated the workflow and it started working again. No idea how it broke down in the first place :confused:
