TypeError: Message must be initialized with a dict: google.ads.googleads.v13.resources.CampaignCriterion

[Eran Mazur]

Good evening, I've been trying to add criterions to a campaign but i receive this error:

  

    criterion.language = lang_resource.resource_name
    ^^^^^^^^^^^^^^^^^^

    self._pb.MergeFrom(self._meta.pb(**{key: pb_value}))
                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Message must be initialized with a dict: google.ads.googleads.v13.resources.CampaignCriterion

This is my code, Any idea what is it? i've searched the internet to see if anyone experienced it also but no luck.

def create_language_op(self, customer_id, campaign_id, lang_name="English"):
googleads_service = self.client.get_service("GoogleAdsService")
criterion_op = self.client.get_type("CampaignCriterionOperation")
query = f"""SELECT language_constant.resource_name FROM language_constant WHERE language_constant.name LIKE '{lang_name}' LIMIT 1"""
response = googleads_service.search(
customer_id=customer_id, query=query
)
lang_resource = response.results[0].language_constant
criterion = criterion_op.create
criterion.campaign = campaign_id
criterion.language = lang_resource.resource_name
return criterion_op
