Getting error on exporting UNDERLYING data of embedded PowerBI report

Manually exporting data from the report opens data.xlsx file with below data

Detail_CountGitHubVersionControlledApps

I am able to retrieve visuals on the page etc. in but not the underlying data from the embedded report

Please see python code used below:

#### Please note I tried using SUMMARIZED instead of UNDERLYING and still same error thrown for 'underlyingData'

exported_data = report.export_visual_data(page_name=report_name, visual_name=visual_name, export_data_type=models.ExportDataType.UNDERLYING)
print(exported_data)

Throws below printed error stack trace:

Also tried below code where it didn't even throw any error but just hung:

exported_data = report.export_visual_data(page_name=report_name, visual_name=visual_name, rows=1, export_data_type=models.ExportDataType.UNDERLYING.value)
