I've updated Kotlin version but nothing else yet so maybe some other dependencies need to be updated

[John O'Reilly]

fyi @bashor

[John O'Reilly]

Tried a different sample (ClimateTrace) and getting different internal error....I'm guessing there probably is some other dependencies that need to be updated first?

[John O'Reilly]

probably ksp at least

[bashor]

@John O'Reilly thanks for trying, could you please file an issue?

[bashor]

also might be worth trying clean build

[John O'Reilly]

Yeah, made sure you to do a clean before hand

[John O'Reilly]

Where do I file the issue again?

[bashor]

kotl.in/issue

[John O'Reilly]

Any particular labels/categories etc?

[bashor]

Subsystems: Backend.Wasm or just add K/Wasm to the title

[shikasd]

Fyi, we changed how composable function types are remapped under the hood in Compose, theoretically any internal errors might be related

[eygraber]

@bashor has the team considered (or is already) using some community libraries/apps as automated test cases?

[Pau Marzo]

Same here

[bashor]

@Pau Marzo did you use production build?
