Hi, Could you check the API version you are using at the moment for this report download? The AdGroupType field was added to the ADGROUP_PERFORMANCE_REPORT <https://developers.google.com/adwords/api/docs/appendix/reports/adgroup-performance-report> in API version v201702 <https://developers.google.com/adwords/api/docs/reference/#new_report_fields>. If you are using an older version of the API, you'll encounter the SelectorError.INVALID_PREDICATE_FIELD_NAME error.
