Issue Checklist

Please confirm the following:

• I have upgraded to the latest
• I have the read the FAQs in the Readme
• I have triple checked, that there are no unhandled promises in my code
• I have set my log level to debug and attached a log file showing the complete request/response cycle
• For bonus points and virtual high fives, I have created a reproduceable git repository (see below) to illustrate the problem

Expected behaviour

I have defined a provider interaction like below. After executing that test and feeding the created PACT file into a stub server, I'd expect to get a successful response for any request in the form of /animals?id=<SOME_NUMBER>.

// Provider interaction in PACT Test
await provider.addInteraction({
  state: "there are animals",
  uponReceiving: "a request for a specific animal",
  withRequest: {
    path: "/animals",
    method: "GET",
    query: {
      id: term({
        generate: "123",
        matcher: "\\d+",
      }),
    },
  },
  willRespondWith: {
    status: 200,
    headers: {
      "Content-Type": "application/json",
    },
    body: {
      id: term({
        generate: "123",
        matcher: "\\d+",
      }),
      name: like("dog"),
    },
  },
});

// ...

// Starting a stub server
import { Stub } from "@pact-foundation/pact-node";

const pactStub = new Stub({ pactUrls: pactFiles, port: 4000, logLevel: "debug" });
await pactStub.start();

Actual behaviour

When the stub server boots, it will print the following error to the console

[email protected]: Pact Binary Error: WARN: Ignoring unsupported matching rules {"match"=>"regex", "regex"=>"\\d+"} for path $['query']$['id'][0]

and any request to /animals?id=<SOME_NUMBER> with SOME_NUMBER !== 123 will yield a 500 response. I have found this issue and this seems to have been a problem in the past that has been fixed already. However, I was not able to get it running with the latest version of @pact-foundation/pact-node.

Steps to reproduce

Thanks for this, apologies for the radio silence - I'm not sure why it didn't get a response earlier.

This may be related to pact-foundation/pact-js#1063, but is more likely related to pact-foundation/pact-mock_service#140
