# multiplatform

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?

I’ve deactivated dce but that didn’t help.

Do you use file level constants?

[Marc Dietrichstein]

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

[Marc Dietrichstein]

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 ?

[Marc Dietrichstein]

The same issue 😕
