This is the Copy/Paste friendly version of the traceback. class="pastemessage">You can also paste this traceback into
a gist:






The debugger caught an exception in your WSGI application. You can now
look at the traceback which led to the error.
If you enable JavaScript you can also use additional features such as code
execution (if the evalex feature is enabled), automatic pasting of the
exceptions and much more.






Console Locked


The console is locked and needs to be unlocked by entering the PIN.
You can find the PIN printed out on the standard output of your
shell that runs the server.
