gettin error on startup command

[hemangjoshi37a]

Code I ran :

import ryven
ryven.run_ryven(
    # args...
)

Error I got :

I'm also seeing a bug with the same command, in this case

TypeError: can only concatenate str (not "NoneType") to str

or when simply running "ryven" from the command line.
