Description
Adds scale-error handling for the dedicated-host
RunInstancespath.RunInstancesdoes not return fleet-styleErrors, so the catch block now checks the thrown AWS SDK errornameagainst configuredscaleErrorsand throwsScaleErrorto trigger retry behavior. The successful response path is split intoprocessRunInstanceResultto validate returned instance IDs.Test Plan
RunInstancesfailed withInsufficientHostCapacity, the error was matched througherror.name, andScaleErrorwas thrown so the request is retried.Related Issues
