Response validation

[alongreyber]

This code does not throw a validation error:

Response.parse_obj(
    {"message" : []}
)

Based on my understanding this should probably throw an error because message is a dict. Let me know if I am missing something.

You're right, this is odd. If "message" is a non-empty list, it seems to fail validation as expected. If the value is the empty string validation passes, but non-empty strings fail. False and 0 also fail validation, so it's not just passing falsy values.

This is a known pydantic bug: pydantic/pydantic#1268
