TL;DR

The issue is likely caused by exceeding the rate limit or connection timeouts, and a workaround could be to implement retry logic with exponential backoff or increase the timeout duration.

Guidance

• Review the error messages to identify the specific cause of the issue, such as rate limiting or connection timeouts.
• Consider implementing retry logic with exponential backoff to handle temporary connection issues.
• Increase the timeout duration to allow for longer connections.
• Verify that the API endpoint is correctly configured and accessible.

Example

// Example of retry logic with exponential backoff
const axios = require('axios');

const retry = async (fn, retries = 3, delay = 500) => {
  try {
    return await fn();
  } catch (error) {
    if (retries > 0) {
      await new Promise(resolve => setTimeout(resolve, delay));
      return retry(fn, retries - 1, delay * 2);
    } else {
      throw error;
    }
  }
};

const makeRequest = async () => {
  return axios.get('https://example.com/api/endpoint');
};

retry(makeRequest).then(response => {
  console.log(response.data);
}).catch(error => {
  console.error(error);
});

Notes

The provided error messages suggest that the issue is related to rate limiting or connection timeouts. However, without more information about the API endpoint and the code making the requests, it's difficult to provide a more specific solution.

Recommendation

Apply a workaround by implementing retry logic with exponential backoff to handle temporary connection issues. This can help mitigate the effects of rate limiting and connection timeouts.
