i was also getting this error, the issue was not with server or with axios or proxy url.
The issue was i wasn’t sending the correct data from my react application.
For Example
i supposed to send:
{ email: 'ib2@gmail.com', password: 'asdf' }

what i was sending is:
{ name: 'ib2@gmail.com', password: 'asdf' }

this caused api don’t understand name field, as i provided email as the key in api.

so if you are still facing the issue try to check if you are sending the correct data.

For every post request, the client first sends an OPTIONS request to check whether the server is ready to accept the connection. You should also allow the server to accept options request. If you have not allowed use the below lines in case of node server

app.use(function(req, res, next) {
   res.header('Access-Control-Allow-Methods', 'POST, GET, OPTIONS');
      next();
});

Axios is a light weight promised based HTTP client for both nodejs and browser.

Let’s see how to handle 400 error message using it.

What is HTTP 400 status code?

HTTP status code 400 is sent by the server in response to our api call if we have a client side error like the data that we sent is invalid in someway like validation issue

Handling 400 error message in Axios

Depedency

Snippet

const axios = require("axios");

const doSomething = async () => {
  try {
    await axios.post("https://httpbin.org/status/400", {});
  } catch (error) {
    console.log(error.response);

    // Check if it's HTTP 400  error
    if (error.response.status === 400) {
      console.log(`HTTP 400 error occured`);
    }
    // You can get response data (mostly the reason would be in it)
    if (error.response.data) {
      console.log(error.response.data);
    }
    // TODO: throw error if you want to handle it somewhere
    // throw error;
  }
};

doSomething();

The 400 Bad Request error is a common issue when making API requests using the popular JavaScript library, Axios. This error can occur for various reasons, including incorrect or missing API request parameters, invalid API endpoint URL, and issues with server-side API handling. In order to resolve the 400 Bad Request error in React.js using Axios, there are several methods that can be tried.

Method 1: Verify API endpoint URL and request parameters

To fix the «Getting 400 error Bad request» issue in Reactjs using Axios, you can verify the API endpoint URL and request parameters. Here are the steps to do that:

First, make sure that the API endpoint URL is correct and valid. You can check the URL by opening it in a browser or using a tool like Postman.
Next, check the request parameters that you are sending to the API. Make sure that the parameter names and values are correct and match the API documentation.
You can also check the data format that you are sending to the API. Make sure that the data is in the correct format and matches the API requirements.
Finally, you can use Axios to make the API request with the correct endpoint URL and parameters. Here is an example code snippet:

import axios from 'axios';

const apiUrl = 'https://example.com/api';
const requestData = {
  param1: 'value1',
  param2: 'value2',
};

axios.post(apiUrl, requestData)
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.log(error);
  });

In this example, we are using Axios to make a POST request to the API endpoint with the request data. If the request is successful, we log the response data to the console. If there is an error, we log the error to the console.

By verifying the API endpoint URL and request parameters, you can fix the «Getting 400 error Bad request» issue in Reactjs using Axios.

Method 2: Add ‘Content-Type’ header to the request

To fix the «Getting 400 error Bad request using axios» in Reactjs using the «Add ‘Content-Type’ header to the request» method, you can follow these steps:

Import axios in your React component:

import axios from 'axios';

Set the headers for the axios request:

const headers = {
  'Content-Type': 'application/json',
};

Make the axios request with the headers included:

axios.post('https://example.com/api', data, { headers })
  .then(response => {
    console.log(response);
  })
  .catch(error => {
    console.log(error);
  });

In this example, we are making a POST request to https://example.com/api with the data and headers included. The headers contain the ‘Content-Type’ key with the value ‘application/json’. This tells the server that we are sending JSON data.

If the server requires a different content type, you can change the value of the ‘Content-Type’ key accordingly.

This method should solve the «Getting 400 error Bad request using axios» issue in Reactjs.

Method 3: Handle API response error using catch() method

To handle API response error using catch() method in ReactJS with Axios, you can follow these simple steps:

Import Axios and create an instance of it:

import axios from 'axios';

const instance = axios.create({
  baseURL: 'https://yourapi.com'
});

Make a request to the API using the instance you just created:

instance.get('/your-endpoint')
  .then(response => {
    // handle successful response
  })
  .catch(error => {
    // handle error response
  });

In the catch() method, you can access the error response and handle it accordingly:

.catch(error => {
  if (error.response) {
    // The request was made and the server responded with a status code
    // that falls out of the range of 2xx
    console.log(error.response.data);
    console.log(error.response.status);
    console.log(error.response.headers);
  } else if (error.request) {
    // The request was made but no response was received
    // `error.request` is an instance of XMLHttpRequest in the browser and an instance of
    // http.ClientRequest in node.js
    console.log(error.request);
  } else {
    // Something happened in setting up the request that triggered an Error
    console.log('Error', error.message);
  }
  console.log(error.config);
});

You can also create a custom error message to display to the user:

.catch(error => {
  const errorMessage = error.response.data.message;
  console.log(errorMessage);
  // display error message to user
});

That’s it! By using the catch() method, you can handle any error responses from the API and display appropriate messages to the user.

Method 4: Check for CORS issues with the API server

If you are facing «Getting 400 Error Bad Request» while using Axios in ReactJS, it might be due to the CORS issue with the API server. To fix this issue, you can check for the CORS issue with the API server. Here is how you can do it:

Step 1: Install Axios

First, you need to install Axios in your ReactJS project. You can install it using npm or yarn. Here is how you can install it using npm:

Step 2: Check for CORS Issue

To check for the CORS issue, you can use the cors-anywhere package. This package allows you to bypass the CORS issue by adding a proxy to your API request.

Here is how you can use cors-anywhere in your ReactJS project:

import axios from 'axios';

const API_URL = 'https://api.example.com';

const corsProxy = 'https://cors-anywhere.herokuapp.com/';

const fetchData = async () => {
  try {
    const response = await axios.get(corsProxy + API_URL);
    console.log(response.data);
  } catch (error) {
    console.log(error);
  }
};

fetchData();

In the code above, we added the cors-anywhere proxy to the API URL. This will bypass the CORS issue and allow us to make the API request without getting the «Getting 400 Error Bad Request» error.

Step 3: Use Axios Interceptors

Another way to fix the «Getting 400 Error Bad Request» issue is by using Axios interceptors. Interceptors allow you to intercept the request or response before they are handled by Axios.

Here is how you can use Axios interceptors to fix the «Getting 400 Error Bad Request» issue:

import axios from 'axios';

const API_URL = 'https://api.example.com';

axios.interceptors.request.use(
  (config) => {
    config.headers['Access-Control-Allow-Origin'] = '*';
    return config;
  },
  (error) => {
    return Promise.reject(error);
  }
);

const fetchData = async () => {
  try {
    const response = await axios.get(API_URL);
    console.log(response.data);
  } catch (error) {
    console.log(error);
  }
};

fetchData();

In the code above, we added an Axios interceptor to set the Access-Control-Allow-Origin header to *. This will allow cross-origin requests and fix the «Getting 400 Error Bad Request» issue.
