StartTime parameter is too far in the past. It must be within the last 18 months.

You can query usage data up to 18 months in the past. The oldest allowed StartTime is 18 months prior to the start of the current UTC day. For example, if the current time is 2021-12-13T5:00:00Z, then you can query usage as far back as 2020-06-13T:00:00:00Z.

This happens if you request Usage Records with a StartTime parameter more than 18 months in the past.

Adjust your StartTime parameter to be at most 18 months in the past.
