Hi Pallavi,
Thank you for posting your concern.
The
INVALID_PREDICATE_FIELD_NAME error occurs when invalid predicate is included in the report. However, you are correct that the
CampaignStatus field is existing in the
Adgroup Performance Report so this error should not be encountered. With this, could you provide the complete
report definition together with the customer ID and error encountered via
Reply privately to author option so I can take a closer look?
