Hi all, This is related to the JS code generated in my multiplatform project. The ktor client gives me

undefined is not an object (evaluating 't.length')

errors when I try to fetch data from a REST endpoint. The problem seems to be related to the buffer module that ktor uses (https://github.com/feross/buffer). It only occurs when using the legacy js backend. Kotlin: 1.4.21 Ktor: 1.5.1 Is anyone familiar with this issue?

Do you use file level constants?

Nope, but I am referencing

const val

Strings (header key definitions) which are defined in an

internal object

when creating a request.

Looks like known problem of top vals in legacy

Thanks for the tip @turansky. I have removed the constants but the issue still persists. Looks like the problem is somewhere else.

What about Kotlin

1.4.30

?

The same issue 😕
