PydanticUserError

[ramedina86]

I've released version 0.1.10 which pins Pydantic to version 1.10.11 and thus solves the issue.

@SergeyPriem Thanks for reporting this

@martinmarroyo I really appreciate your help on this. As I wrote above, I decided to pin the Pydantic version for now.

The code you wrote seems to address the demands of Pydantic 2, but, as you noted, problems remain (an exception coming from the ASGI application).

I believe that this is a FastAPI issue. Pydantic v2 support was added in the latest version of FastAPI (0.100) and there appears to be some growing pains judging by discussions / issues on their repository. Thankfully, FastAPI decided to keep backwards compatibility with Pydantic v1 which allows to use the latest FastAPI while staying on Pydantic v1.

Update

After some more research, I found that my issue was primarily caused by the new Pydantic update to version 2.0.2 last week. I fixed it temporarily by downgrading to version 1.10.11 (pip install pydantic==1.10.11). That should get things working as expected for now until a more permanent fix is put in place.

I ran into the same issue when installing streamsync 0.1.9 and running streamsync hello on Python 3.11. Here is the relevant documentation from Pydantic: https://docs.pydantic.dev/dev-v2/usage/errors/#typed-dict-version. This is breaking the streamsync command in general. I modified the imports in ss_types.py to check for the python version and import TypedDict based on that. Here is what I added to ss_types.py:

import sys
from typing import Any, Dict, List, Literal, Optional, Protocol, Tuple
# Python versions earlier than 3.12 need typing_extensions.TypedDict
if sys.version_info.major <= 3 and sys.version_info.minor < 12:
    from typing_extensions import TypedDict
else:
    from typing import TypedDict
from pydantic import BaseModel

It got the streamsync command to work, but now I'm getting validation errors when running streamsync hello.

I'd like to help with troubleshooting this further, but am admittedly a little lost with respect to collaboration on this project and how to build to test my changes. @ramedina86 I'm happy to help, please let me know if that's something you would like.
