Understanding the Problem with axios.get for HTTPS Requests in Node.js

If you're working with Node.js and trying to send an HTTPS GET request using Axios, you might run into errors that aren't immediately clear. While developing with Axios version 0.21.1, a common issue arises where an error occurs during the log statement but the error object returned in the catch block appears empty. This can lead to confusion and slow down your development process.

In this guide, we will break down this problem and help you understand how to correctly use axios.get to send HTTPS requests, particularly focusing on handling authorization headers and logging responses properly.

The Problem Explained

You attempted to send a GET request with authorization using this code snippet:

However, you encountered an error indicating that something went wrong, which led to the catch block being executed. The peculiar part was that the error object was empty, suggesting that the underlying issue was related to how you were trying to log the response.

Why Does This Happen?

Logging Issues: When logging the getRes object using JSON.stringify(getRes), it causes an error. This is because getRes contains circular references that cannot be serialized into JSON. Hence, your program enters the catch block unnecessarily.

Unauthorized Errors: You noted receiving a 401 Unauthorized error, even when using the correct Bearer token in Postman for the same URL. This could be due to issues in the request format or headers used in your Axios call compared to Postman.

How to Correctly Use axios.get

Adjusting Your Logging

To resolve the first issue with the logging, you can either skip using JSON.stringify() entirely on the response object or log only the data contained in getRes. Here’s how you can fix your code:

Handling Headers and Authorization

Ensure that you are using the correct format for headers. In your second snippet, which uses {} or null, you can see that the authorization header might not be applied correctly, resulting in the 401 Unauthorized error:

The correct approach is to specify the headers in the first parameter as shown in the corrected code earlier, as Axios accepts the configuration for the request in the third argument.

Checking for Error Handling

Finally, ensure your error handling also accounts for the fact that you cannot directly stringify the error object returned in the catch block. Properties like error.message can provide useful context, so consider logging those specifics:

Conclusion

Handling HTTPS GET requests using Axios in Node.js can seem daunting, especially when debugging issues related to authorization and logging. By understanding how Axios handles responses and errors, you can implement correct logging and authorization headers to avoid unnecessary pitfalls.

Remember, always log the response directly or the specific data intended, rather than trying to stringify objects that may contain circular references. This simple adjustment can save you from a lot of confusion and wasted debugging time.

With these insights, you're now equipped to tackle errors when sending HTTPS GET requests using Axios smoothly. Happy coding!
