hey we re upgrading from ktor 1 4 to ktor 1 6 and are encountering an `IllegalStateException` when trying to use our ktor client to call a ktor server for our integration tests anyone able to take a look This is the error message when `customPost ` is called `Failed to parse request body request body length should be specified chunked transfer encoding should be used or keep alive should be disabled connection close ` setup ``` val httpClient = HttpClient CIO expectSuccess = false suspend inline fun lt reified TRequestData gt customPost url String requestCacheKey String requestContent TRequestData headers Map lt String String gt = null contentType ContentType = ContentType Application Json <http httpClient post|httpClient post> lt HttpResponse gt url var contentAstString = requestCacheManager getOrCreateRawString requestCacheKey requestContent returns a string headers forEach headerKey value gt header headerKey value body = TextContent contentAstString contentType ```

Failed to parse request body: request body length should be specified, chunked transfer encoding should be used or keep-alive should be disabled (connection: close)

setup:

Copy code

val httpClient = HttpClient(CIO) {
    expectSuccess = false
  }

suspend inline fun <reified TRequestData> customPost(
    url: String,
    requestCacheKey: String,
    requestContent: TRequestData,
    headers: Map<String, String>? = null,
    contentType: ContentType = ContentType.Application.Json
  ) {
        <http://httpClient.post|httpClient.post><HttpResponse>(url) {
            var contentAstString = requestCacheManager.getOrCreateRawString(requestCacheKey) { requestContent } // returns a string
            headers?.forEach { headerKey, value ->
                header(headerKey, value)
            }
            body = TextContent(contentAstString, contentType)
        }
  }

so i added logging with the client config and it started working

Copy code

this.HttpClientLogging {
      level = Level.TRACE
    }

Could you please share information about a response from a server that causes client to throw

IllegalStateException

the ktor server in this case is returning an HTTP 202 Accepted

Copy code

call.response.status(HttpStatusCode.Accepted)

i changed the endpoint on the server to

Copy code

call.respond(HttpStatusCode.Accepted)

and it fixed it

Unfortunately, I cannot reproduce

IllegalStateException

using Ktor 1.6.1

Hey, each server handler should call

call.respond

explicitly It was a bug that using of just

call.response.status(HttpStatusCode.Accepted)

was allowed and it was reason of freezes in some cases.
