Issues arise when attempting to retrieve information in NextJS from a local API

One of my coworkers has created a backend application using Spring Boot. Strangely, I can only access the API when both our computers are connected to the same hotspot. If I try to access the other computer's API and port through a browser or Postman, I am able to retrieve data from the REST API without any issues

However, when I attempt to fetch data using Axios or the fetch() method in my application,

the fetch method responds like this:

and Axios responds like this:

Can anyone provide guidance on how to resolve this issue?

PS: I have included the temporary code snippet for fetching here.

Answer №1

There could possibly be a CORS authorization issue, additional information is required for further troubleshooting.

We suggest enabling CORS for the resetApi application as a potential solution.

Answer №2

To resolve CORS issue,

The axios method is one way to address it.

If you are using an Express app, ensure it has CORS (Cross-Origin Resource Sharing) enabled by adding the following snippet to your server file:

// Ensure this is already declared in your API file
var app = express();

// ADD THIS
var cors = require('cors');
app.use(cors());

Additionally, when utilizing the fetch method, remember to include async and await.
