Saving draft metadata for a platform services add-on fails repeatedly in the Developer Dashboard. The GraphQL mutation OCDevManagePlatformServicesAddOnMetadataEnableAdvancedModeModalMutation returns error code 1675030 with message "Error performing query." This issue occurs on the add-on metadata configuration page when attempting to enable advanced mode, consistently failing on each save attempt and preventing users from persisting draft changes to add-on metadata.
