I'm trying @MockBean but I get an error.

[j1cs]

I am using @MockBean using request and response objects but I get an error.

Log: https://gist.github.com/j1cs/28a777381df18c30e6679b8ac4144fac#file-mock-error-log
Sample project: https://github.com/j1cs/micronaut-error-mock/blob/master/src/test/java/me/jics/base/MathControllerTest.java#L34

when I run the test in debug mode I can see that mathService.compute(request) returns null
I think my problem is the way I do the mock .when() and .then()

What am I doing wrong?

[j1cs]

Adding @EqualsAndHashCode I solved.
