Why Does the Form Trigger Node Not Open the Form in Test Mode?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I configured the “Form trigger” node in my n8n workflow, but when I test it the form does not open automatically. Instead, I see the message “Waiting for you to submit the form”.

Here’s my setup and what I’ve observed:

I’m using n8n version 1.77.3 on Windows via npm with a Postgre database. When I click test, nothing appears automatically and no form is opened.

Expected Behavior:

In test mode, clicking the Test URL should open a form in a new browser tab or window. You must then complete and submit the form to trigger the node’s execution.

Additional Information, in case it helps troubleshoot:

Check if your browser pop-up blocker is preventing the form from opening.
Make sure you are using the Test URL and not a production URL, since the editor UI does not display data for production workflows.

Below is the output from the last node for reference:

BASH
Information on your n8n setup
-----------------------------
* **n8n version:** 1.77.3
* **Database (default: SQLite):** PostGre
* **n8n EXECUTIONS_PROCESS setting (default: own, main):**
* **Running n8n via (Docker, npm, n8n cloud, desktop app):** npm
* **Operating system:** Windows (last)

I’m looking for clarification whether this behavior is expected in test mode or if there’s a configuration issue on my part.

Based on the documentation for the Form Trigger node, the message “Waiting for you to submit the form” indicates that the node is listening for a form submission rather than an error with its configuration. Here are a few points and troubleshooting steps to consider:

Expected Behavior When Testing

In test mode (using the Test URL) the node waits until you submit the form data. It doesn’t automatically simulate a submission.
When you click either Test Step or Test Workflow, n8n is designed to open the form in a new browser tab or window. You must then fill out and submit that form to trigger the node’s execution (or to simply observe the incoming data).

Troubleshooting Steps

Manually Open the Test URL:
- Ensure you click (or copy/paste) the Test URL into your browser. If your browser is blocking pop-ups, this could prevent the form from opening automatically.
Browser Pop-up Settings:
- Check your browser’s pop-up blocker settings. Allowing pop-ups from your n8n instance URL can help ensure that the test form opens in a new tab.
Test Mode vs. Production Mode:
- Confirm you are using the Test URL and not the Production URL during development/testing. In production mode, data is not displayed in the editor UI.
Workflow Activation:
- While testing, the workflow need not be active. However, if you have switched to using production mode without activating the workflow, you might not see the expected behavior in the editor UI.

Summary

The message “Waiting for you to submit the form” is normal when using the Form Trigger node in test mode—it simply means that n8n is waiting for you to open the test URL and submit the form. Check that your browser allows the form to open, and if necessary, manually open the Test URL provided by the node panel.

Hope this helps resolve your testing issue!
