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 <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

this.HttpClientLogging {
      level = Level.TRACE
    }

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

[Justin Moy]

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

[Justin Moy]

call.response.status(HttpStatusCode.Accepted)

[Justin Moy]

i changed the endpoint on the server to

call.respond(HttpStatusCode.Accepted)

and it fixed it

[Aleksei Tirman [JB]]

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.
