lateinit initialization error when using createChatCompletion()

[BrianJr03]

When I attempt to use createChatCompletion(), I always receive this error:

lateinit property response has not been initialized

Here the function I am using

fun chat(text: String): String {
        messages.add(text.toUserMessage())
        val response = openai.createChatCompletion(request)
        messages.add(response[0].message)
        return response[0].message.content
}

I checked out OpenAI.createChatCompletion() and I can see that response is the lateinit variable that apparently isn't being initialized.

val httpResponse = client.newCall(httpRequest).execute()
lateinit var response: ChatResponse
OpenAICallback(true, { throw it }) {
    response = gson.fromJson(it, ChatResponse::class.java)
}.onResponse(httpResponse)

return response

val httpResponse = client.newCall(httpRequest).execute()
lateinit var response: ChatResponse
OpenAICallback(true, { throw it }) {
    response = gson.fromJson(it, ChatResponse::class.java) // initialized here
}.onResponse(httpResponse)

return response

Can you triple-check that you are on the correct version (Currently 1.3.0)?

I just ran this to confirm, it works for me:

So I checked and I am on 1.3.0 and it wasn't working. Out of curiosity, I downgraded to 1.2.7 and it worked. I then went back to 1.3.0 and it still works. I'm really not sure what happened here.

Glad you got it fixed. If you build something cool, feel free to share it in discussions.

I get this error:
