I'll also mention another error I started encountering:

> Task :site:kspKotlinJs FAILED
e: java.lang.AssertionError: Built-in class kotlin.Number is not found

But I only get this when building in a docker container.

Did you ensure the kobweb and kotlin and compose versions match?

[Ryan Scott]

That's a good point. I'm just going to downgrade until I can fix the other issues.

Here's what was working for me:

jetbrains-compose = "1.6.11"
kobweb = "0.19.0"
kotlin = "2.0.10"
