Description

Please add a clear and concise description of what the bug is.

Steps to reproduce

self.iaas_client.get_server(self.config.stackit.project_id, server.id, details=False) # succeeds
self.iaas_client.get_server(self.config.stackit.project_id, server.id, details=True) # crashes with

Multiple matches found when deserializing the JSON string into AllowedAddressesInner with oneOf schemas: str. Details

It's obvious this fails because the validators are just parsing strings

    # data type: str
    oneof_schema_1_validator: Optional[Annotated[str, Field(strict=True)]] = Field(
        default=None, description="Object that represents an IP address."
    )
    # data type: str
    oneof_schema_2_validator: Optional[Annotated[str, Field(strict=True)]] = Field(
        default=None, description="Classless Inter-Domain Routing (CIDR)."
    )

but from_json asserts that only one schema must validate

        if match > 1:
            # more than 1 match
            raise ValueError(
                "Multiple matches found when deserializing the JSON string into AllowedAddressesInner with oneOf schemas: str. Details: "
                + ", ".join(error_messages)
            )
