I see your point but that's what logs show:
When enable_ai_max is set to *True*:
operations {
update_mask {
paths: "resource_name"
paths: "ai_max_setting.enable_ai_max"
}
update {
resource_name: "customers/{CustomerID}/campaigns/{CampaignID}"
ai_max_setting {
enable_ai_max: true
}
}
}
And all is working fine, setting is updated.
When enable_ai_max is set to *False*:
operations {
update_mask {
paths: "resource_name"
}
update {
resource_name: "customers/{CustomerID}/campaigns/{CampaignID}"
ai_max_setting {
enable_ai_max: true
}
}
}
So when set to False, *paths: "ai_max_setting.enable_ai_max" *disappears
and setting is not updated.
Here's the code I'm using:
campaign_service = self.client.get_service("CampaignService")
campaign_operation = self.client.get_type("CampaignOperation")
campaign = campaign_operation.update
campaign.ai_max_setting.enable_ai_max = True #False
campaign.resource_name = campaign_service.campaign_path(
str(client_id), str(campaign_id)
)
self.client.copy_from(
campaign_operation.update_mask,
protobuf_helpers.field_mask(None, campaign._pb),
)
campaign_response = campaign_service.mutate_campaigns(
customer_id=str(client_id), operations=[campaign_operation]
)
