ScalaMock - "Unexpected call" error when the call is defined

So I have this test (unfortunately I can't include the full code and failed to reproduce a simplified version):

"create method" should {
    "return OK" in {
        val offerService: OfferService = mock[OfferService]
        (offerService.create _).expects(offer).returning(Future(Left(Created())))
        val controller = new OfferController(offerService)
        val request = FakeRequest(POST, "/offer").withJsonBody(Json.toJson(offer))
        val result: Future[Result] = call(controller.create, request)
        status(result) must be (201)
    }
}

that is failing with this error:

[info] create method
[info] - should return OK *** FAILED ***
[info]   Unexpected call: <mock-1> OfferService.create(Offer(PixelSlate))
[info]   
[info]   Expected:
[info]   inAnyOrder {
[info]     <mock-1> OfferService.create(Offer(PixelSlate)) once (never called - UNSATISFIED)
[info]   }
[info]   
[info]   Actual:
[info]     <mock-1> OfferService.create(Offer(PixelSlate)) (Option.scala:121)

Am I missing something obvious here? The mocked method is called only once. Why is it saying the method was called and then not called at the same time?

Not really enough information to answer why this occurs. You don't show what offer is, yet the question hinges on the == contract of that type being content equality and not reference equality. If that type behaves funny, and is beyond your control, then use predicate matching instead: https://scalamock.org/user-guide/matching/
