Hi Eray, Thanks for reaching out to the Google Ads API Support team.
With regards to your concern, I checked the error that you encountered "FIELD_HAS_SUBFIELDS" in Google Ads API documentation this error meaning is "The field mask updated a field with subfields. Fields with subfields may be cleared, but not updated. To fix this, the field mask should select all the subfields of the invalid field". Also, If you want to know more about this error you can check this documentation FieldMaskError for more information on this. Let us know if you have any further questions.
