Hello :wave:

Got an error:
```I am experiencing Expected `ComposeExperimentalHotReloadSettings {..}`, but got `scalar````
I’m trying to enable `hotReload` in projects module desktop-app.

Here are the project configs.

*project.yaml* 
```modules:
  - ./shared
  - ./desktop-app
  - ./android-app```
*desktop-app/module.yaml*
```product:
  type: jvm/app

dependencies:
  - $compose.desktop.currentOs
  - $compose.material3
  - ../shared

settings:
  compose:
    enabled: true
    experimental:
      hotReload: enabled
  jvm:
    mainClass: MainKt```

Hi there
Thanks for reaching out

The cryptic error message you experience has been fixed recently, but the fix hasn't been shipped into the 0.8.1

This message basically occurred because there is no more property `settings::compose::experimental::hotReload::enabled`

Instead, Compose Hot Reload now works just if `settings::compose::enabled` is `true`

However, since you use the stable IDE (which is old from the Amper POV) which is supposed to work with older version of Amper, it is highly recommended to upgrade to the latest EAP when trying Amper, because otherwise this feature won't work anyway

Sorry for the inconvenience, it was conscious thing, for now Amper version is effectively bound to the IDE version, it's a limitation we have in order for us to move quickly

we try to keep backward compatibility though, but in this case, it was easier to break things

Hello Anton :wave: So the `hotReload` is a thing of the past and I need to use EAP with `0.8.1` version, is that correct?

enabling hot reload is a thing of the past, it should work automatically without enabling

&gt; and I need to use EAP with `0.8.1` version,
correct

I see, thank you for the swift reply :bow:
