Why is mockk executing a method when I'm checking for not invoked scenario?

Question

I have a scenario like

fun someMethod() {
   try {
       val response = callApi.method()
       val output = processResponse(response)
   } catch (throwable: Throwable) {
   }
}

Now I'm testing for the scenario when callApi.method() throws an exception and the method processResponse() is not invoked. It is working as expected but mockk is failing

verify(exactly = 0) { processResponse(any()) }
verify { processResponse(any()) wasNot Called }

with this error:

java.lang.NullPointerException: Parameter specified as non-null is null

My question is that why mockk is trying to execute the processResponse() method with a null response from any() when I'm just verifying that the method is not invoked? Are there any other ways to avoid this error? Thanks
