Context
testExceptionHandlinginteg test in the Cloudwatch test package was flakey because the service was returning a non deterministic exception. We expected it to returnMissingParameterexception but it sometimes returnedInvalidParameterCombinationexception instead.I was able to reproduce it by running test case repeatedly 100 times, seeing the following:
79/100
MissingParameter21/100
InvalidParameterCombinationFix
The fix adds all the other required fields, except for
MetricName. Resulted in deterministic 100/100MissingParameterexception.
