swagger-mock-validator does not work when the OASv3 has a pattern on the path param

[Former user]

When my API in open-api-v3 has a pattern on the path parameters, swagger-mock-validator fails to validate with a weird error. Example shown below. Can you verify if this is a known bug in the tool.

pact.json

Results in the following error:

This looks like it may have been an issue with the regexs used rather than an issue with this tool. I was able to successfully get 0 errors 0 warnings with these files once I updated the regexs in the pact and swagger files.

Pact regex - remove one of each of the double back slashes in the path:

        "matchingRules": {
          "$.path": {
            "match": "regex",
            "regex": "\/helloworld\/v1\/healthcheck\/[0-9a-f]{8}-[0-9a-f]{4}-[0-5][0-9a-f]{3}-[089ab][0-9a-f]{3}-[0-9a-f]{12}"
          }

Swagger regex - remove the trailing slash at the end:

            "schema": {
              "type": "string",
              "pattern": "^[0-9a-f]{8}-[0-9a-f]{4}-[0-5][0-9a-f]{3}-[089ab][0-9a-f]{3}-[0-9a-f]{12}$"
            }

I think this issue can probably be closed as a non-issue, as it appears this tool already supports this functionality.
