This issue seems to be a limitation within the GA4 API, particularly in relation to how dateHourMinute dimension interacts with the Default Channel Grouping dimension. Currently, it doesn’t appear that the GA4 API supports a dimension filter for Default Channel Grouping when dateHourMinute is selected. The official documentation provided by Google within their Dimensions and Metrics Explorer doesn’t list any workaround either. It might be helpful to continue monitoring Google’s updates for any added functionalities in the future. For now, you might consider manipulating the gathered data post-extraction or using other APIs that allow for more flexibility with dimensions. It is also possible that creating a custom dimension that categorizes channels like the Default Channel Grouping may solve the issue.
