After update: Provider state parameters not rendered into contract JSON for request path parameters

Software versions

• OS: Mac OSX 12.5
• Pact Node version: @pact-foundation/pact-core@13.7.7
• Node Version: v16.15.1
• Other Versions: Pulled as dependency of @pact-foundation/pact@10.1.1

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

When writing a consumer test, where the setup uses a fromProviderState() matcher on a request path parameter, the resulting Pact JSON file should contain a generator and matchingRule for this provider state parameter.

Actual behaviour

After updating from @pact-foundation/pact@10.0.2 to @pact-foundation/pact@10.1.1, the Pact JSON file does not contain a corresponding generator/matchingRule.

This is only true for path parameters - for provider state parameters from query parameters or body parameters, this still works as expected.

Steps to reproduce

E.g. with the provider-state-injected example (https://github.com/pact-foundation/pact-js/tree/master/examples/v3/provider-state-injected):

• Run the consumer contract test & save the resulting pact JSON file
• Upgrade the pact dependency in the package.json from 10.0.2 to 10.1.1
• Run the consumer contract test again & compare the resulting JSON files

This is what I get:

None

I hope this is the right repo to open this issue - if it should go to pact-js instead, let me know and I can open it there instead 🙇

Can also confirm from our side that it works again 👍 Thanks for the quick fix!
