Pydantic 2 does not support all of the V1 capabilities

[chrand]

hello. Trying to launch zwave-js-server-python, but it terminates with import error. Install was done with pip3 install zwave-js-server-python Launching it, I get the error below:

$ ./zwave-js-server-python

Downgrade pydantic to 1.10 and everything should work as is. Thanks for the report though, maybe we aren't as ready for pydantic 2 as we thought

[chrand]

np. happy to have helped testing. thanks for a nice client library!

It seems like its available in the v1 shims, so that is surprising:

$ pip3 install pydantic==2.4.2
$ python3
>>> from pydantic.v1 import create_model_from_typeddict
>>> 

[raman325]

hmm that's weird. @chrand is it possible you were on an earlier version of v2 that didn't have this shim?

[allenporter]

Is this just an older version of zwave-js-server-python without the shims? Seems like it could be based on the line numbers.

Edit: Yeah, would be helpful to know version of zwave-js-server-python and pydantic involved
