[QUESTION] Getting "Connection refused: no further information" when calls skrape.it exctract methods from submodule

[ZhestovskyYS]

Hi! I want to use skrape.it to parse kotlin.lang documentation. I've created submodule ":parse" in project and calls extract method from its' class

    class ExtractUseCase {
    suspend operator fun invoke() = skrape(AsyncFetcher) {
        var header = ""
        request { KOTLIN_DOCS }
        response {
            htmlDocument {
                header = parseHeader()
            }
        }
        return@skrape header
    }

    private fun Doc.parseHeader(): String {
        var header = ""

        h1 {
            findFirst { header = text }
        }

        return header
    }
}

So, for a test I call it from main and before it added local call:

suspend fun main() {
    extracted()
    withContext(Dispatchers.IO) {
        println(ExtractUseCase().invoke())
    }
}

private suspend fun extracted() {
    withContext(Dispatchers.IO) {
        skrape(AsyncFetcher) {
            request { url = "https://kotlinlang.org/docs/unsigned-integer-types.html" }
            response {
                htmlDocument {
                    h1 {
                        findFirst {
                            println(text)
                        }
                    }
                }
            }
        }
    }
}

And the output is:

Unsigned integer types

Sorry, I didn't set url and userAgent in invoke method.

operator fun invoke(): String = skrape(BrowserFetcher) {
    var header = ""
    request {
        url = KOTLIN_DOCS
        userAgent = "Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"
    }
    response {
        htmlDocument {
            header = parseHeader()
        }
    }
    return@skrape header
}
