The dpaste support portal is for problems with dpaste itself, not other technical/programming questions.
So, where should you look for people to help you with the code/error you posted here?
Django help: A lot of dpaste users are working with Django. An excellent place for live help with Django problems is the #django channel on Libera.Chat. Another help resource is the Django Users Google Group.
Other help: In addition to doing a web search for support/community forums related to the tech in question, I recommend searching the hundreds of channels on Libera.Chat; they can be a great a fast source of help. https://libera.chat/guides/findingchannels
