Call n8n Workflow Tool - Workflow selector doesn't list workflows and Execute Workflow Trigger is missing (v2.30.4)

Questions
1

Hi everyone,

I’m trying to implement an AI Agent using Call n8n Workflow Tool on n8n v2.30.4 (hosted by Cloudfy).

I’ve read the documentation and several community topics, but I’m still unable to configure the tool.

Current behavior

When configuring the Call n8n Workflow Tool, I see the message:

“This tool will call the workflow you define below, and look in the last node for the response. The workflow needs to start with an Execute Workflow Trigger.”

However:

  • I cannot find any node called Execute Workflow Trigger or When Executed by Another Workflow.
  • Searching for workflow, execute, or another only shows Execute Sub-workflow.
  • The Workflow selector stays on “Choose…” and clicking it does not list any workflows.

Environment

  • n8n version: 2.30.4
  • Hosted by Cloudfy
  • PostgreSQL database
  • AI Agent node available
  • Call n8n Workflow Tool available

What I already verified

  • The workflow exists and is saved.
  • PostgreSQL credentials and queries are working correctly.
  • Other workflows execute normally.
  • I compared my interface with the official documentation and community examples.

Questions

  1. Is Execute Workflow Trigger expected to exist in n8n 2.30.4?
  2. Has it been renamed in newer versions?
  3. Are there any requirements for a workflow to appear in the Workflow selector?
  4. Could this be related to Cloudfy’s deployment or configuration?

I’ve attached screenshots showing:

  • the tool configuration,
  • the empty workflow selector,
  • and the node search results.

Any guidance would be greatly appreciated.

Thank you!

Hi @Janete_Oliveira Welcome!
The node still exists, it was renamed and it only shows up under trigger nodes. Open the sub-workflow on its empty canvas, click “Add first step”, and pick “When executed by another workflow”. Searching the normal node panel returns “Execute Sub-workflow” because that is the caller node, so the trigger will never appear there.
Once the sub-workflow has that trigger and is saved, go back to the Call n8n Workflow Tool, keep Source on “Database”, and switch the Workflow selector from “From list” to “By ID”, then paste the ID from the end of the sub-workflow’s URL. That skips the list completely. If By ID connects fine while the list stays empty, the list is failing to load on your host and your configuration is not the problem.
