Workflows Error out, but don't show any error message or execution data and don't trigger error workflow

Describe the problem/error/question

in n8n 1.116.2 - I have workflows that seem to fail as shown in the screenshot, but when I go to that execution in it’s history, there’s no error message or execution data. Additionally, the error workflow for that is not triggering either which makes identifying the issue near impossible.

What is the error message (if any)?

Please share your workflow

Information on your n8n setup

  • n8n version: 1.116.2
  • Database (default: SQLite): Postgres
  • n8n EXECUTIONS_PROCESS setting (default: own, main): queue
  • Running n8n via (Docker, npm, n8n cloud, desktop app): EKS
  • Operating system: Linux

That’s strange, and you actually have several successful runs. Are you sure the subworkflow trigger isn’t receiving some incorrect data? Or maybe something is happening with the data structures you’re using (the ‘data tables’), since they were implemented recently?!

I’m sorry, but could you explain in more detail what’s happening in the Executions tab? For example, in that specific failed run, are you unable to click any of the buttons like "Debug in editor”, “Log”, or “Retry”?

When there is an error in the trigger in a workflow, no execution is created and error workflow run with a difference input, you do not have the execution entry (there is no execution) and instead you have a trigger entry
