i All,
I am developing an app that handles marketing campaigns.
Now I am trying to implement the new Google Goal Optimized Shopping Campaign. I have everything set at an account level and I am able to create the goal optimized campaigns from the AdWords interface, but when trying to publish a campaign through the API, every time I get the same error. I tested my implementation with both v201802 and v201806 API versions.

Thank you in advance for any help,
Bogdan
