#1434 stateHandlers Ignored, Verifier Attempts Local /_pactSetup Call When requestFilter Is Present Issue created by madhulikamitra ### Software versions Please provide at least OS and version of pact-js OS: macOS (arm64) Consumer Pact library: Pact-JS v13.2.0 Provider Pact library: Pact-JS v13.2.0 (with pact-core@15.2.1) Node Version: v18.20.2 ### 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 and have read the section on intermittent test failures • 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 configuring the Verifier with a stateHandlers object that defines a no-op function for a provider state (e.g., "quote can be created"), the verifier should: Execute the stateHandlers function locally. Not send any HTTP requests for state setup (e.g., no POST to http://127.0.0.1:/_pactSetup). Proceed directly to verifying the interaction against the providerBaseUrl (<>). The stateHandlers should override the default state setup behavior, especially when the provider doesn’t require external setup. ### Actual behaviour Despite defining a stateHandlers function for "quote can be created", the verifier: Registers the handler (logs show it’s configured) but does not execute it (no handler logs appear). Sends a POST request to http://127.0.0.1:/_pactSetup (e.g., 127.0.0.1:52667), which times out after 30 seconds because no local server is running. Fails with: MismatchResult::Error("Invalid response: error sending request for url (http://127.0.0.1:/_pactSetup)", None). This happens even with a no-op stateHandlers function and persists whether requestFilter is present or not (though the presence of requestFilter might exacerbate or alter the behavior). ### Steps to reproduce Install Pact-JS: npm install @pact-foundation/pact@13.2.0. Create a Pact file at pacts/consumer-pact.json with the contents below. ### Relevant log files consumer-pact.json `const path = require('path'); const { Verifier } = require('@pact-foundation/pact'); const PROVIDER_NAME = 'provider'; const CONSUMER_NAME = 'consumer'; const baseUrl = 'my-servivce-url'; const pactDir = path.resolve(process.cwd(), 'pacts'); // Mock request filter const requestFilter = (req, res, next) => { console.log('Request filter called for:', req.method, req.path); req.headers['content-type'] = 'application/json'; req.headers['accept'] = 'application/json'; next(); }; describe('Pact Verification for ForexV3-Funding', () => { it('validates forex quote endpoint expectations against local pact', async function () { this.timeout(60000);

const localPactFile = path.join(pactDir, `${CONSUMER_NAME.toLowerCase()}-${PROVIDER_NAME.toLowerCase()}.json`);

const verifier = new Verifier({
  provider: PROVIDER_NAME,
  providerBaseUrl: baseUrl,
  pactUrls: [localPactFile],
  stateHandlers: {
    'quote can be created': () => {
      console.log('State handler for "quote can be created" executed');
      return Promise.resolve();
    }
  },
  requestFilter, // Comment this out to test without it
  customProviderHeaders: [
    'Content-Type: application/json',
    'Accept: application/json'
  ],
  logLevel: 'DEBUG'
});

try {
  await verifier.verifyProvider();
  console.log('Pact verification successful for local file');
} catch (err) {
  console.error('Pact verification failed:', err);
  throw err;
}

}); });`_Please ensure you set logging to`DEBUG` and attach any relevant log files here (or link to a gist)._ Comment out requestFilter in the Verifier options and rerun to see if the behavior changes (testing your hypothesis). pact-foundation/pact-js
