I have many issue with ktor, I changed behavior my code but I still don't result and response in iOS

my code on common:

    private val client = HttpClient()
    fun about(callback: (String) -> Unit) {
        GlobalScope.apply {
            launch(ApplicationDispatcher) {
                val result: String = client.get {
                    url("https://google.com")
                }

                callback(result)
            }
        }

    }

and my code on Android that It's work:

        APIPresentation().about {
            try {

                print(it)
            } catch (e: Exception) {
                e.printStackTrace();
            }

        }

and my Code on iOS that not response and print exception:

io.ktor.client.call.ReceivePipelineException: Fail to run receive pipeline

 let presenetation = APIPresentation();
        presenetation.about { (s) -> KotlinUnit in
            print(s);
            
            return KotlinUnit();
        }
       

Where is problem?

Hi @ImanX, thanks for the report. Could you provide the stacktrace and cause?

[ImanX]

Hi @e5l , No because xcode only print log that.

[icarumbas]

Hey @ImanX and what does it print?

[ImanX]

@icarumbas in xcode log just print io.ktor.client.call.ReceivePipelineException: Fail to run receive pipeline

[icarumbas]

I've got the same error with alike code, and i've noticed that it works with some other sites, for example
"https://stackoverflow.com". I'm not web developer, and i don't know what is difference between google and other sites, but this may help, i think.

I get this after packaging a Ktor API with distZip, running the binary on a raspberry pi, and trying to fetch an endpoint that makes an http client request. Running locally works. Thought maybe the stack trace would help

(UPDATE: my issue was a timeout error cause it was so slowwww on the Pi)

For the url("https://google.com") I've got:
Cause: kotlin.IllegalArgumentException: Charset ISO-8859-1 is not supported

It looks like we should find the way to decode ISO-8859-1 in kx.io.

This problem is very similar to #787

Hi, I was trying to follow this below give Kotlin example for Multiplatform:
https://medium.com/@aldychris/kotlin-multiplatform-for-ios-and-android-mobile-application-96a753e175f7

I have successfully run it but now I am getting error. Fail to run receive pipeline, after searching a lot and trying to find original exception it seems like it is illegalStateException:

Hey, I got this problem at the JVM.

I use CIO as my engine on version 1.1.2 and my simple program is JVM based.
Essentially, my code looks like this:

fun main() {
    runBlocking {
        val client = HttpClient(CIO)
        val response = CommonAPI.client.get<String> {
            url {
                protocol = URLProtocol.HTTPS
                host = "playlisten.rbb-online.de"
                encodedPath = "/radioberlin/main/index.php"
            }
        }
        println("'$response'")
        client.close()
    }
}

I get the stack:

I know that the title indicates iOS, but it's pretty similar and the same code works for different websites as described above.

EDIT: changed version

Hi @molikuner, thanks for the report.
Could you file the separate issue for that case?

[cy6erGn0m]

Fixed in 1.1.3.
