This happens when html5lib.serializer.serialize gets unexpected argument.

Code to reproduce the exception:

from html5lib.html5parser import parse
from html5lib.serializer import serialize
token_stream = parse('<html><body><p>Hi!</p></body></html>')
serialize(token_stream, omit_optional_tag=False)


---------------------------------------------------------------------------

TypeError: __init__() got an unexpected keyword argument 'omit_optional_tag'

Fixed version of the code:

from html5lib.html5parser import parse
from html5lib.serializer import serialize
token_stream = parse('<html><body><p>Hi!</p></body></html>')
serialize(token_stream, omit_optional_tags=False)


<html><head></head><body><p>Hi!</p></body></html>
