Have a little problem pulling report from Google Ad Manager API based on startDate and endDate. Tbh I actually confused with the date format. Based on this link it ISO 8601’s format ‘YYYY-MM-DD'”. but when I run the query I got this error:

In the documentation, it says ‘There is a type mismatch in the request (e.g., an integer field has a string value).’. I get it, it probably confused with ‘-‘ symbol (i.e. 2024-04-21), so I deleted the ‘-‘ symbol and left it with integer values (i.e. 20240421). I ran my script again and I got this error . In the documentation it says that this error => ‘Indicates that an unexpected error occured.’ and I don’t know what the ‘@’ symbols mean?

 # Create report job.
  report_job = {
      'reportQuery': {
          'dimensions': ['DATE', 'AD_UNIT_NAME'],
          'dimensionAttributes' : 'AD_UNIT_CODE',
          'adUnitView': 'FLAT',
          'reportCurrency': 'MYR',
          'columns': ['TOTAL_LINE_ITEM_LEVEL_IMPRESSIONS',
                      'TOTAL_LINE_ITEM_LEVEL_ALL_REVENUE'],
          'dateRangeType': 'CUSTOM_DATE',
          'startDate':'2024-04-29',
          'endDate':'2024-05-05'

      }
  }

My Query to pull report.

I just want to pull historical report weekly based on specific startDate and endDate but I actually have no idea how the startDate and endDate work. I read the API document but still im confuse. Help will appriciated.
