How can I validate integer enum values in Pact JS?

[OS-teresamarcelino]

I am working with Pact and have an enum that consists of integer values between 0 and 2. I initially tried using regex('0|1|2', "1"), but the generated contract JSON file treats the value as a string type instead of an integer.

Since the enum values are integers, I need a way to validate them as integers within the contract, rather than as strings. What is the recommended approach to properly validate these integer enum values in Pact? Should I use a different matcher for integer validation, or is there a better way to handle this scenario?

Any insights or best practices would be greatly appreciate
