#475 [Stub server] Ignoring unsupported matching rules Issue created by OskarLebuda Description Hello everyone! ✌️ After generating a Pact and running the stub server, it fails to accept the syntax of the generated Pact, displaying the error message:

[10:18:42.822] ERROR (71098): pact-core@14.0.6: Pact Binary Error: WARN: Ignoring unsupported matching rules {"$.password"=>{"combine"=>"AND", "matchers"=>[{"match"=>"type"}]}, "$.username"=>{"combine"=>"AND", "matchers"=>[{"match"=>"type"}]}} for path ['body']

[10:18:42.822] DEBUG (71098): pact-core@14.0.6: WARN: Ignoring unsupported matching rules {"$.access_token"=>{"combine"=>"AND", "matchers"=>[{"match"=>"type"}]}} for path ['body']

[10:18:42.822] ERROR (71098): pact-core@14.0.6: Pact Binary Error: WARN: Ignoring unsupported matching rules {"$.access_token"=>{"combine"=>"AND", "matchers"=>[{"match"=>"type"}]}} for path ['body']

I've tried to use all available version like

PactV3

and

PactV4

, additionally I've tried to use specification version 3 and 4. Every single time I've got an error described down below. I would like to use StubServer to provide the mocks for my fronted app. I have created a reproducable git repository to illustrate the problem. All you need to do is clone this repo and run specified commands (see below) Software versions • OS: MacOS Sonoma 14.2.1 • Pact Node version: • `@pact-foundation/pact`: 12.1.2 • `@pact-foundation/pact-core`: 14.0.6 • Node Version:

v18.19.0

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 Stub server runs correctly with generated pact. Actual behaviour Steps to reproduce • Clone repository • Run

npm install

(remember to use node >= 18) • Run

npm run test

• Run

npm run start-stub

Result: Stub server shows error with ignoring unsupported matching rules Relevant log files
