@dosubot[bot] commented on GitHub (Feb 13, 2026):

This appears to be related to a recent instability in the human-in-the-loop feature. The human input functionality was implemented and then immediately reverted on January 30, 2026, which may have left the system in an inconsistent state where emails are still being sent but the endpoints don't work correctly.

URL format issue: The email link you received (/form/cn1Ti9rKDQNAx1NGwuQ0MF99) appears to be missing parts of the expected path. Based on the API routing code, the correct format should be:

  • https://your-domain/api/form/human_input/cn1Ti9rKDQNAx1NGwuQ0MF99

Workaround: Try accessing the form using the full API path above instead of just prepending your homepage URL.

Since the feature was recently reverted, this may be a known issue that the team is working on. You may want to watch for updates in future releases.

To reply, just mention @dosu.

To correct URL in the email, you should specify APP_WEB_URL in your .env file then stop and start the instance.

@QuantumGhost commented on GitHub (Feb 14, 2026):

@HZJprince It seems like this is a deployment-related issue. To facilitate the debugging process, could you please provide the following information?

  1. Network request logs and browser console logs for the form page.
    You can collect the network logs using the following steps:

    a. Open the Chrome Developer Tools.
    b. Paste the link received in the email and navigate to the form page.
    c. Export the requests using the Export HAR (sanitized) feature, as shown in the image below:

    Image

  2. The configuration values for CONSOLE_API_URL, CONSOLE_WEB_URL, and APP_WEB_URL.

  3. The request routing details for your Dify instance. Is there any intermediate reverse proxy? If so, how does it handle requests?
