API Feedback

i have built an html page that using node.js and the assistant API. for the last week when i send prompts about 25% of the time i fail to get a response. is this a known problem. any suggestions ? My code looks like this: console.log(Adding message to thread ID ${thread_id}...);
await openai.beta.threads.messages.create(thread_id, { role: ‘user’, content: message });

    console.log("Running the thread...");
    const runResponse = await openai.beta.threads.runs.create(thread_id, { assistant_id });
    const runId = runResponse.id;
    console.log("Run created with ID:", runId);

    let runStatus = runResponse.status;
    let runResult;
    const timeout = 60000; // Timeout duration in milliseconds (e.g., 60 seconds)
    const startTime = Date.now(); // Track when polling started

    // Poll for completion
    while (runStatus === 'queued' || runStatus === 'running') {
        console.log("Polling run status:", runStatus);

        // Check if the timeout has been exceeded
        if (Date.now() - startTime > timeout) {
            console.log("Polling timed out");
            return {
                statusCode: 504, // Gateway Timeout status code
                body: JSON.stringify({ error: 'Request timed out' }),
            };
        }

        await new Promise(resolve => setTimeout(resolve, 5000)); // Wait for 5 seconds before polling again
        try {
            runResult = await openai.beta.threads.runs.retrieve(thread_id, runId);
            console.log("Poll Result:", runResult);
            runStatus = runResult.status;
        } catch (pollingError) {
            console.error("Error during polling:", pollingError);
            return {
                statusCode: 500,
                body: JSON.stringify({ error: 'Error during polling', details: pollingError.message }),
            };
        }
    }

    if (runStatus === 'completed') {
        // Retrieve messages from the thread
        try {
            const threadMessages = await openai.beta.threads.messages.list(thread_id);
            const assistantMessage = threadMessages.data[0];
            const messageValue = assistantMessage.content[0].text.value;
            return {
                statusCode: 200,
                body: JSON.stringify({ message: messageValue }),
            };
        } catch (retrievalError) {
            console.error("Error retrieving messages:", retrievalError);
            return {
                statusCode: 500,
                body: JSON.stringify({ error: 'Error retrieving messages', details: retrievalError.message }),
            };
        }
    } else {
        console.log("Run did not complete successfully:", runResult);
        return {
            statusCode: 500,
            body: JSON.stringify({ error: 'Run did not complete successfully', details: runResult }),
        };
    }
} catch (error) {
    console.error("Error:", error);
    return {
        statusCode: 500,
        body: JSON.stringify({ error: error.message }),
    };
