Mark, I just realised the cause behind it giving me a Http404. The reason is it is trying to access http://localhost:8001/3.0/lists/2 where 2 is the List id of 'maillist2@example.com' If it sends a request to http://localhost:8001/3.0/lists/maillist2@example.com, then it would work fine. What could be the possible reason behind this? (It sending a request to http://localhost:8001/3.0/lists/<list_id> and not http://localhost:8001/3.0/lists/<LISTNAME>)

Sorry for the late reply, Mark. I just checked it. mailman lists shows maillist2@example.com as a component of the output. Also, localhost:8001/3.0/lists/maillist2@example.com/ shows full JSON details about mailllist2@example.com. { "display_name": "Maillist2", "fqdn_listname": "maillist2@example.com <mailto:maillist2@example.com ", "list_id": "maillist2.example.com <http://maillist2.example.com>", "list_name": "maillist2", "mail_host": "example.com <http://example.com>", "member_count": 3, "volume": 1, "description": "NA", "self_link": "http://localhost:8001/3.0/lists/maillist2.example.com", "http_etag": "\"d4966cd892c82a3dbbe663fe41e321ff166a4c5b\"" }

But the hyperkitty send button is still showing the KeyError named 'file'. Its traceback being the one I sent before.

As I have tried to say a few times and explicitly said at < https://mail.python.org/archives/list/mailman-developers@python.org/message/...

...

, KeyError named 'file' is not the issue.

The issue is the part of the traceback leading up to and including (in your case)

During handling of the above exception (HTTP Error 404: b'404 Not Found'), another exception occurred:

which appears to say that localhost:8001/3.0/lists/some_list_name/ is returning a 404. Is maillist2@example.com the listname part of the URL of the HyperKitty page from which you are trying to send.
