Error when I want to execute another workflow

Questions
1

Hi,

I made a workflow 6 months ago, it was currently activated everyday. This workflow called another workflow in my database and everything worked fine.

However, since two days, I am meeting this error : ERROR: Target workflow may not be called.

I am on version 1.22.6 of n8n, would you have an idea of my problem ?

  • Database : postgres
  • Running n8n via : Docker
  • Operating system: n8n-io

Thanks,
Ben

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:

Hi @BenJ :wave: Would that by chance a workflow from before you started using version 1 or higher of n8n?

If you could also share any other logs, that would be helpful!

Hi @EmeraldHerald,

I was using this this workflow with version 1.2.1 at the beginning and maybe the version 1.1.1 I think, do I have to delete the node and recreate it ?

My entire error is :

Hi @BenJ - perhaps give that a try, or also check into looking at updating your workflow ID, as they haven’t looked like that for quite a few releases :sweat_smile: But you may need to delete the node and try with a newer version, too. They’re a string of alphanumeric characters, now :+1:
