Getting these sorts of erroneous type errors all over a mixed Java/Kotlin module. (required type: T provided: T 🙃)
Compiles fine however. Build #IU-251.26927.53 - ❗*Only occurs when K2 is enabled* ❗- known issue?

Found "IDEA-127767 Editor reports incompatible type error, but required type is the same as the found type", but it's very old. The symptom, at least, is back 💀

Could you please let us know what are the signatures of the containing call and the requestDTO.getDescription()? Also please specify how many JDKs do you have and iff they are different on the call site and where the methods are declared. Thanks!

I’m seeing this as well. Here’s my Java code snippet from the screenshot:

@Test
  public void resource() throws ExecutionException, InterruptedException {
    var expected = "sitrus";
    String actual = PokeApi.getDefault().getBerryAsync(10).get().getName();
    assertEquals(expected, actual);
  }

what are the signatures

getName() here is from a val name: String on a Kotlin data class

Also please specify how many JDKs do you have

JDK is set to 21 via toolchain in Gradle.

and if they are different on the call site and where the methods are declared

The call site and the declaration are in the same module. It’s a Kotlin Multiplatform module. The declaration is in commonMain/kotlin, while the call site is in jvmTest/java.

Similar but different error if I call inline instead of using a `var`:

and another where it just can’t resolve `List<>.get`:

[Sargun Vohra]

Using a variable there gives me “unknown class”

[Sargun Vohra]

(all of this compiles fine, runs, and tests pass; just the IDE is wrong)

[Anna Kozlova]

So you have java in common code? Sorry, seems I don't get it at all 😕

[Sargun Vohra]

I have Kotlin in common code. Java in jvmTest code, because I want to make sure my library is usable from Java

[Sargun Vohra]

Library is 100% Kotlin Multiplatform, there’s a little Java in the tests just in the jvmTest source set

[Anna Kozlova]

Can you probably share a project without code (only dependencies/structure)?

[Sargun Vohra]

I can share the code, it’s an open source library

[Sargun Vohra]

pushing up the branch now

I see red code, will try to investigate. Thanks again!
