AWS API Gateway Query parameter validation - api

Question

I have been trying to validate my request parameters using x-amazon-apigateway-request-validator, but unfortunately it is not working. Below is swagger file-

I am trying to validate my request parameters against some regex and enum values.
I am not sure if this is even possible or not. Can anybody please help me with this?

Answer 1

For HTTP parameter validation, API Gateway only supports marking one as 'required'. It does not support regex/enum values for parameters.
