Describe the problem/error/question

I got this error when trying to use Execute Workflow to run other workflows, my current plan is FREE, and looks like it can’t use this node, I wanna know if we have another solution for this?
I’m just having an idea about Webhook Node (Resources for this gonna very high if I have 4-5 workflows are listening on the same time)

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:

DB_TYPE: Postgres
Operating System: Ubuntu 22.04

The node is available for free, so in every plan. Sounds more like something is going wrong in a HTTP Request node in the sub workflow. So I would open that specific sub workflow execution and check out what is going on.

Many thank Jan, looking forward to getting the solution on this.
FYI: I’m using this docker-compose
I just modified the DB environment to DB_POSTGRESDB_USER=${POSTGRES_USER}, running on local and protocol is http

Wait, The error is about the HTTP Request Node, it has nothing in common with the Execute Workflow node :thinking:

Can you share the workflow(s)?

Ow, thank for pointing it out. I made a mistake. I thought it was about the main-workflow not sub-workflow.
Thank you very much!
