When I try to do this

val = file.extra_info

I get this error

TypeError: initializer for ctype 'struct SNDFILE_tag *' must be a cdata pointer, not NoneType

I am able to do this just fine tho

print(file.extra_info)

I want to put thew value of extra_info into a json response

This sounds like the file might not contain any extra info?
