I have an issue with Java usage from Kotlin. I’m trying Micronaut with Kotlin. I’m trying to handle exception in the rest stack and when I write the following code:
124 val error: JsonError = jsonError 125 .link(Link.SELF, Link.of(request.uri)) 126 127 return HttpResponse 128 .status<JsonError>(httpStatus) 129 .body(error)
I get the following error:
Controller.kt:[129,23] Type mismatch: inferred type is io.micronaut.http.hateoas.JsonError! but io.micronaut.http.hateos.JsonError? was expected
The jsonError object is a Micronaut Java class and the link(…) call line 125 is inferred as a JsonError!
But the HttpResponse.body(@Nullable body) method is annotated with @Nullable so the inferred type is JsonError? and here I get my error. How could I fix this issue?
