Hi, I am using ktor client on iOS and trying to move API requests to background thread, but get this error:

Trying to access top level value not marked as @ThreadLocal or @SharedImmutable from non-main thread

My code is

...
withContext(workerDispatcher){
    val loginResponse = <http://client.post|client.post><LoginNetworkResponse>("$apiEndpoint/init/auth?v=1") {
            contentType(ContentType.Application.Json)
            body = LoginNetworkRequest(
                ...
            )
        }
   ....
}

This is bug. No workaround.

[Aleksey Chugaev]

Has it been raised anywhere for tracking?

[cy]

Yes, we aware of it: we have tons of top-level vals that don’t work with K/N. Need to cleanup them somehow.

[Aleksey Chugaev]

Do you have a target release or date for it yet?

[cy]

I hope 1.3.0

[cy]

1.3.0-rc still doesn’t work

[Aleksey Chugaev]

No it doesn't, I updated to RC today
