Model can't be used since datapoint_uri validation doesn't return a value

Lines 30 to 33 in da99984

	@validator("datapoint_uri", always=True)
	def validate_datapoint_uri(cls, value):
	if len(value) < 10:
	raise ValidationError("datapoint_uri need to be at least 10 char length.")

I think pydantic validator should return the value at the end of the function? Now the model can be used only for validation.
