The error you’re encountering, POST api/v1/country_list 400 (Bad Request), usually indicates that the request being sent to the server has some invalid data or formatting issue that the server cannot process.

Here are some steps to troubleshoot and resolve the issue:

  1. Check the API endpoint: Ensure that the URL 'api/v1/country_list' is correct and the server is expecting a POST request at this endpoint. Sometimes a missing base URL (e.g., 'https://yourdomain.com/') can cause issues if you’re not sending the request to the correct server.
  2. Validate the request payload: If the POST request is supposed to send data, you need to include the payload (e.g., JSON object) in the axios.post() call. For example:
const handleLogin = (e) => {
  axios.post('api/v1/country_list', {
    // Replace with actual data expected by the API
    key1: 'value1',
    key2: 'value2',
  })
  .then(result => {
    console.log(result);
  })
  .catch(error => {
    console.log(error);
  });
}

If the server expects specific data (like headers or a body), and you’re not passing that, you’ll get a 400 Bad Request.
3. Inspect the server response: The 400 Bad Request error usually comes with additional details in the response that might help pinpoint the issue. You can log the full error response like this:

.catch(error => {
  if (error.response) {
    // The request was made and the server responded with a status code
    console.log('Error data:', error.response.data);
    console.log('Error status:', error.response.status);
    console.log('Error headers:', error.response.headers);
  } else if (error.request) {
    // The request was made but no response was received
    console.log('Error request:', error.request);
  } else {
    // Something happened in setting up the request that triggered an error
    console.log('Error message:', error.message);
  }
});
  1. Check server-side API requirements: Verify the API documentation to see what the server expects in the request (e.g., parameters, headers, or authorization tokens). You may need to add headers like:
axios.post('api/v1/country_list', data, {
  headers: {
    'Content-Type': 'application/json',
    // Add any other headers like Authorization if required
  }
})

By logging more detailed information about the error and validating the request format, you’ll have a better understanding of why the server is rejecting it. Let me know if you need more help based on the error response details!
