Getting the below error while running pact test in the consumer side... i might be doing something really stupid but just can't figure out what...

  })

  const expectedBody = { status: true, data: [{ fullName: 'dummy' }] }

  before(() => provider.setup())

  after(() => provider.finalize())

  afterEach(() => provider.verify())
