Solutions

1. Use a supported GroupBy.Type such as DIMENSION or TAG.
2. Check the GetCostAndUsage GroupBy parameter in the request.

When it happens

Trigger: Thrown at src/main/java/io/github/hectorvent/floci/services/ce/GroupAggregator.java:101 when the library encounters an invalid state.

Common situations: Occurs when a GetCostAndUsage request uses a GroupBy type other than DIMENSION or TAG. Use Type=DIMENSION with a supported Key, or Type=TAG.
