Hi team,
I am facing this "headers have already been sent" error in an AJAX
call. I am not able to fix it. I need your hellp. Would be better if
someone could explain this issue.
2020-03-04 11:00:45,582 Trac[main] ERROR: [172.24.188.116] Internal Server
Error: <RequestWithSession "POST '/admin/pros users/users'">, referrer

RuntimeError: headers have already been sent
Above chunk is the error. And below is how I write my json response to the
AJAX call.
def respond(self, req, data, code=200):
"""Respond to the JSON request by sending the JSON-encoded data
back."""
json_data = json.dumps(data)
req.send_response(code)
req.send_header('Content-Type', 'application/json')
req.send_header('Content-Length', len(json_data))
req.write(json_data)
raise RequestDone
Not sure if I am missing any code here in this respond method. Welcome your
suggestions to fix this error.
