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

Tests run like before.

Actual behaviour

Tests fail with an error message:

Steps to reproduce

We are having trouble running our tests in CI since the update of @pact-foundation/pact to version 12.1.2. Consumer message pact tests fail with the below error. Reverting to 12.1.2 lets the test run successfully again.

Tests run with Jest look like this:

it("something works", async () => {
  const messageRequest = {
    someId: Matchers.string("Nkiwmu-oFoRN3lqzYD7M"),
    originalFileChecksum: {
      algo: "SHA256",
      hash: Matchers.hexadecimal("b3eb64161ac2a85bf364fc3b0e19e063bc9375475237feddee2ae36089c59cb3"),
    },
    someOtherId: Matchers.string("T-PlRCvy2N3JnjAiANGC"),
    fileName: Matchers.string("some-file.bmp"),
    profile: Matchers.string("thumb"),
    targetFormat: Matchers.string("jpg"),
  };

  let result: MessageResponse | undefined = undefined;
  let message: Message | undefined;
  const ackMock = jest.fn();
  const nackMock = jest.fn();

  await converterPact
    .given({ name: "A file to convert", params: { mediaType: "image" } })
    .expectsToReceive("A valid convert image request")
    .withMetadata({
      type: "convert:image",
    })
    .withContent(converterRequest)
    .verify(async (m: PactMessage) => {
      message = new Message(m.contents, m.metadata);
      message.ack = ackMock;
      message.nack = nackMock;

      const channel = amqpService.getChannelFromPool("Exchange/Queue/convert");
      result = await (channel.consumer as Pipeline<Message, MessageResponse>).execute(message);

      return result;
    });

  expect(message).not.toBeUndefined();
  expect(nackMock).not.toHaveBeenCalled();
  expect(ackMock).toHaveBeenCalled();
  expect(result).not.toBeUndefined();
});

Relevant log files

No special logs are emitted from Pact, however running the same test with Pact version 12.1.2 (where the test works) emits the following logs:

[mefellows]

Thanks for spotting, this is indeed a bug. It looks like pactffiMessageGivenWithParams was not exported by the C interface in @pact-foundation/pact-core.

I'll push out a release shortly that pins the versions so that an upgrade will automatically pull in the correct version.

Fixed in 12.3.1 via 34d8a4b.
