Non-informative error.

Description

I clnstantly get com.aallam.openai.api.exception.GenericIOException: Failed to parse HTTP response: unexpected EOF exception and don't know what is wrong.

Steps to Reproduce

1. I create quite big ChatCompletionRequest (I don't get this error on short requests, when arrayOfValues.size == 170 for example)
2. Send it by Chat.chatCompletion(), the suspend one.
3. Get this error.

Environment

• openai-kotlin version: 3.4.1
• Kotlin version: 1.9.10
• OS: Windows 11

Additional Info

ChatCompletionRequest

If this is unusable I am happy to provide ChatCompletionRequest in some other shape or form.

I simply call val completion = openAI.chatCompletion(chatCompletionRequest) where openAI defined like this:

 private val openAI = run {
        val config = OpenAIConfig(
            token,
            organization = organization,
            logging = LoggingConfig(logger = Empty),
        )
        OpenAI(config)
    }

pretty straightforward

[aallam]

This appears to be an error from the underlying HTTP client. Could you please share which one you were using? As a workaround, have you tried using a different HTTP client?

[kverty]

I don't think this error happens in my code. You see, I put two logs this way:

logger.info {
    "GPT Completion request: ${json.encodeToString(ChatCompletionRequest.serializer(), chatCompletionRequest)}"
}
val completion = openAI.chatCompletion(chatCompletionRequest)
logger.info {
    "GPT Completion response: ${json.encodeToString(ChatCompletion.serializer(), completion)}"
}

Only the first one was printed. So error happens inside openAI.chatCompletion(chatCompletionRequest) call.

I see that httpClient is created here from config.

public fun OpenAI(config: OpenAIConfig): OpenAI {
    val httpClient = createHttpClient(config)
    val transport = HttpTransport(httpClient)
    return OpenAIApi(transport)
}

In my config I fill out only 3 fields: token, organization and logging. All the others are default. And it worked until now. Upd. Maybe not exactly "now", I don't really know when it started to fail:) Do you think I should specify proxy argument of config?

[aallam]

I was actually referring to Ktor's HTTP client engines (such as okhttp or apache), which one did you use in your gradle dependencies ?

[kverty]

In jvmMain we used CIO. You use my gradle dependencies when creating httpClient by createHttpClient(config), not just config?

[aallam]

Yes, the engine you've chosen is used by the underlying Ktor client. The error is more likely related to the CIO engine. For JVM, I would recommend trying with OkHttp instead.

Fixed by doing

 private val openAI = run {
        val config = OpenAIConfig(
            token,
            organization = organization,
            logging = LoggingConfig(logger = Empty),
            timeout = Timeout(15.minutes, 20.minutes, 25.minutes)
        )
        OpenAI(config)
    }
