Hello there! I am trying to switch the Javascript part of multi-platfatform library to IR. But now things do not compile anymore and I get the error below.
Does anyone know what is going on there? Things work fine with the Legacy compiler.

Here is the class that causes the compilation error. Any clue what I can do?

package de.peekandpoke.ultra.common

        /**

        fun of(builder: Builder.() -> Unit) = Builder().apply(builder).build()
    }

        }

        fun build() = TypedAttributes(entries.toMap())
    }

        return entries[key] as T?
