After upgrading my project to 2.0.20-RC and running js browser test which renders an html like this: <img src="/image.png"> I'm seeing some strange messages in the console. More in thread.

It's a lot of text like this:

[Robert Jaros]

There is no such problem with Kotlin 2.0.0.

[Robert Jaros]

The test itself is working correctly (green) despite these messages.

[Artem Kobzar]

@Ilya Goncharov [JB] ^^

[Ilya Goncharov [JB]]

Do you have reproducer? I tried with just adding <img src="/image.png"> with and without image.png in project, and I don’t have such warnings

[Robert Jaros]

Nothing simple enough at the moment.

[Robert Jaros]

But I'll try to prepare one.

[Robert Jaros]

But probably after the weekend.

[Ilya Goncharov [JB]]

So, I guess that the root cause is that we add now following lines

"proxies": {
    "/": "/base/kotlin/"
  }

They are necessary for successful loading of wasm files if they exist (in Kotlin/Wasm target)

So it is useful to investigate this weird behaviour because both Kotlin/JS and Kotlin/Wasm targets can suffer because of that

[Robert Jaros]

yes, Kotlin/Wasm has the same effect

[Robert Jaros]

only in browser tests, node tests are working ok
