• 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

Expected behaviour

Provider Verification passed sucessfully

Actual behaviour

TypeError: Cannot read property 'forEach' of undefined

Steps to reproduce

Run the provider file

`import { Verifier } from '@pact-foundation/pact';
import path from 'path';

describe('Pact Verification', () => {
jest.setTimeout(50000);
it('validates the expectations of dynamicApi Service', () => {
const opts = {
log: path.resolve(process.cwd(), 'logs', 'pact.log'),
LogLevel: 'debug',
providerBaseUrl: 'providerBaseUrl',
pactBrokerUrl: 'pactBrokerUrl',
pactBrokerToken: 'pactBrokerToken',
pactUrls: [
'pactUrls',
],
publishVerificationResult: true,
providerVersion: '2.0.0',
provider: 'provider',
tags: ['release'],
};
return new Verifier(opts).verifyProvider().then((output) => {
console.log('Pact Verification Complete!');
console.log(output);
});
});
});
`

Here is the output

`FAIL contract-testing apps/contract-testing/provider/dynamicApi.spec.ts

[mefellows]

Can you please re-test with the latest @ghsouza89? This should be fixed now. Thanks again for raising it.

[ghsouza89]

@mefellows here is the result after update the @pact-foundation/pact-core to 13.13.5

Before run I did the follow steps:

1. rm -rf node_modules
2. rm -f package-lock.json
3. npm cache clean --force
4. npm install

[TimothyJones]

@pact-foundation/pact-core is a dependency. You need to update @pact-foundation/pact

[TimothyJones]

You can do npm ls @pact-foundation/pact-core to see what you have

[ghsouza89]

npm ls @pact-foundation/pact-core

here is the output:

$ npm ls @pact-foundation/pact-core themarkerr@1.4.0 C:\markerr-app +-- @pact-foundation/pact@11.0.0 | -- @pact-foundation/pact-core@13.13.4
-- @pact-foundation/pact-core@13.13.5

This illustrates the problem. You need to bump the version of @pact-foundation/pact to the latest (and remove the other pact-core dependency, you don't need to depend on it directly). The latest is 11.0.2, although I believe this was fixed in 11.0.1.

Apologies for not being clear about this the first time.
