Hi Afsane, Please note that not all campaign types will allow you to adjust bids. Based on your error, it looks like you are trying to mutate a criterion that isn't mutable for your campaign type. Can you please provide complete logs of the request/response to the API so that I can better investigate what is causing the "This operator cannot be applied to a criterion of this type" error?
In the meantime, you may find this guide helpful as it outlines bid adjustment eligibility for each campaign type.
