Hey Hemant,

Sorry for the trouble... The code is broken since the cryptography library got updated.

You may refer to the report for the details on the last known good code and libraries.

You can now look at the traceback which led to the error. To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

dump() shows all variables in the frame dump(obj) dumps all that's known about the object
