Package fails to Import

[deuelvogel]

After installing the package using pip (pip install asyncapi-schema-pydantic) and trying to import in python, we see the following error:

raise PydanticUserError(
pydantic.errors.PydanticUserError: A non-annotated attribute was detected: is_object = <asyncapi_schema_pydantic.v2_3_0.json_schema.cached_property object at 0x000002349877D310>. All model fields require a type annotation; if is_object is not meant to be a field, you may be able to resolve this error by annotating it as a ClassVar or updating model_config['ignored_types']
