Describe the problem/error/question

I ran docker compose logs on a n8n container and I am seeing this error JSON parameter needs to be valid JSON. …How can I find out what process is and specially what node is.

What is the error message (if any)?

On your dashboard, go to the ‘Executions’ tab and then select ‘Error’ as the status. This will show you all workflow executions that could have generated that error. That should be a great starting point!
