Pact Verification Failed for multipart/form-data request

[dula85]

I am writing consumer pact test and application is react and test frame work is jest enzyme.
multipart/form-data request as bellow,

pactWith({ consumer: "example-react-site", 
           provider: "example-api",
           logLevel:"debug",
           port: 1234
        }, provider => {
    beforeAll(() => {
        provider.removeInteractions();
    });
    beforeEach(() => {
        Constants.baseUrl = provider.mockService.baseUrl;
    });

    describe("example api endpoint", () => {
        beforeEach(async () => {
            const file = path.join(__dirname, "./", "new_file.txt");
            const data = fs.readFileSync(file);
            const rawData = atob(data);

Behaviour:
I am getting Pact verification failed as bellow,

  console.error

  console.error
    Pact verification failed!

Pact between example-react-site and example-api › with 30000 ms timeout for Pact › example api endpoint › should send document to sign

using,
jest: 26.0.1
jest-pact: 0.5.4

But if I remove generated log file and run pact test it will run successfully all the time.
wonder what is happening and possible fix.

I don't think this is related to jest-pact, but what does the log at path/pact/logs/mockserver-integration.log show?

[TimothyJones]

I'll close this for now as it hasn't had any activity and I don't think it's a jest-pact issue.

Feel free to re-open if you think it needs further attention.
