Fix issue with ssm variables not found

The variable resolution for ss has the possibility when a parameter is not foudn to use a fallback value, that is based on the error code. The V3 error code is not the same then the v2 one, for the ease I just check also for the v3 code, as it is the only place in the core code to check for the that kind of code
