Crash when start a HubConnection

[topanim]

an incomprehensible conflict, I am inclined to believe that the cause is the dependency versions.

I tried:

• To change the versions to the one in the library.
• emove your client (but then it crashes with an error: exactly the same conflict with respect to the HttpTimeout plugin)

What could be the reason?

code:

hubConnection = HubConnectionBuilder.create(
            "wss://domain/path?id=$myId&access_token=$token"
        ) {
            transportEnum = TransportEnum.WebSockets
            httpClient = client
            skipNegotiate = true
            automaticReconnect = AutomaticReconnect.Active
            logger = mylogger
        }

hubConnection.start()

stacktrace:

my client:

HttpClient(get()) {
            install(WebSockets)
            install(HttpTimeout) {
                socketTimeoutMillis = 30_000
                connectTimeoutMillis = 30_000
                requestTimeoutMillis = 30_000
            }
            install(ContentNegotiation) { json(get()) }
            followRedirects = false
        }

ktor version: 3.0.0-wasm2

Yeah, I have not tried ktor version 3 yet nor do I specify support for web assembly. I will look into it though, probably this sunday or following week.

[topanim]

Thanks for the reply.

I don't have to use version 3.x.x, but lowering the version didn't help either. What can be done to make the project work?

[lepicekmichal]

Okay, I can't see the problem then. Could you share a demo project producing this error?
