flutter http.post is giving 500 error, while the api is working fine in postman

This login API is working fine in postman, but I am getting 500 status code error in flutter.

Below is the code for service where api being called:

import 'dart:convert';
import 'package:http/http.dart' as http;
...

class AuthService {
  static const API_URL =
      "http://ec2-15-185-73-129.me-south-1.compute.amazonaws.com";
  static const headers = {
    'Content-Type': 'application/json'
  };
  Future<APIResponse<AuthResponse>> signIn() async {
    var body = jsonEncode({"username": "username", "password": "password"});
    var response =
        await http.post(API_URL + "/api-token-auth", headers: headers, body: body)));
    print(response.body.toString());
    print(response.request.toString());
    if (response.statusCode == 200) {
      // not reaching here
    } else {
      print(handleError(response.statusCode));
      // response.statusCode is **500**

    }
  }
}

print(response.body.toString()) gives below output:

I got this error because I passed some wrong parameters in the body of my request. I would say check properly the body you're passing to your request.

For anyone who has this issue it may be that the Host header is not being sent properly. I tested in postman and was quite surprised to find that this was the cause of my problem

The 500 status code means that The server encountered an unexpected condition which prevented it from fulfilling the request. Please Check the url or add \ after the url like this:

 var response =
    await http.post(API_URL + "/api-token-auth\", headers: headers, body: body)));

Replace the URL:

API_URL + "/api-token-auth"

With

API_URL + "/api-token-auth/"

Its a little weird. Maybe something wrong with your server-side routing but with the trailing / its working.
