Need help with TypeError: Cannot read properties of undefined (reading ‘stream’)

[Reowolfnus]

This my code and I get this error when I call run for my thread:

console.log(req.body.prompt);

const thread = await openAI.beta.threads.create({
    messages: [{
        role: "user",
        content: [{
            type: "text",
            text: req.body.prompt,
        }],
    }],
});

const assistantFilePath = "./assistant.json"
const assistantData = await fsPromises.readFile(
    assistantFilePath,
    "utf8"
);
assistantDetails = JSON.parse(assistantData);
assistantId = assistantDetails.assistantId;

console.log(assistantId);

const run = await openAI.beta.threads.runs.create({
    threads_id: thread.id,
    assistant_id: assistantId,
});

let message = await openAI.beta.threads.runs.retrieve(
    thread.id, run.id);

while(message.status !== "completed") {
    await new Promise((resolve) => setTimeout(resolve, 1000));
    message = await openAI.beta.threads.runs.retrieve(
        thread.id, run.id);

    if(message.status.includes(["failed", "cancelled", "expired"])) {
        console.log(
            `Run status is ${message.status}. Chat paused...`
        );
        break;
    }
}

const messages = await openAI.beta.threads.messages.list(thread.id);

const messageToBeShown = messages.data
.filter((msg) => msg.run_id === run.id && msg.role === "assistant").pop();

if(messageToBeShown) {
    console.log(messageToBeShown.content[0].text.value + "\n");
}

res.send(messageToBeShown.content[0].text.value + "\n");

})

The error:
