Dify version

0.6.9

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

  1. Use HTTP Request with DELETE method on workflow.
    image
    Regardless of its status(this time, the URL will not work because it has not opened), it returns Node (node-name) run failed: argument of type 'NoneType' is not iterable.
    This might relate to how http(or ssrfproxy) request handles DELETE inside source code, as only DELETE uses requests library with some polyfills while all other methods use httpx.

✔️ Expected Behavior

Should return a response, or corresponding error.

❌ Actual Behavior

Request is sent, but causes error regardless of response.
