Why is Response.parsed Optional?

[johnthagen]

I generated a Python client and the types.py has this:

@attr.s(auto_attribs=True)
class Response(Generic[T]):
    """A response from an endpoint"""

    status_code: int
    content: bytes
    headers: MutableMapping[str, str]
    parsed: Optional[T]

I was curious. What is the situation where parsed is None? Is this signaling an error in parsing? Something else?

[johnthagen]

It seems as if having incorrect authentication can return None. Perhaps this should be added to an attribute docstring parsed?

It will be None anytime there is no response. If there's a schema for an error (e.g. 401) then that data should be parsed, so it's not everytime there's an error, just when there's no response.
