Can't activate a workflow 404 error

Hi, I can’t activate a previously working flow, I get a 404 error when trying to.
I’ve updated to the latest stable version but no change. Last time I encountered the problem, updating the version was enough to solve this.

Any clue ?
Thakns in advance

Information on your n8n setup

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:

So I noticed you can duplicate the flow. The new one will activate, the old one will not even if they are the same… Pretty odd.

Hi @Damien_Busch1 ,

Like we’ve discussed over email, we’ve raised an internal ticket about this to try and understand what is blocking you. But we’ll share the results here as well to share our findings with the rest of the community :slight_smile:

Hi @Damien_Busch1

Does the workflow activation work when you only have one lemlist node trigger? Perhaps we can isolate it down to one specific trigger node that is causing this. Thanks for the testing :slight_smile:
