Angular 15: HttpClient post not sending body as JSON in the request
I keep running into Hey everyone, I'm running into an issue that's driving me crazy. I tried several approaches but none seem to work. I've been struggling with this for a few days now and could really use some help. I'm working with Angular 15 and I'm having trouble with the `HttpClient` when trying to send a POST request. I expect the request to send a body in JSON format, but the server is receiving it as an empty object. Here's the code I have for my service: ```typescript import { Injectable } from '@angular/core'; import { HttpClient, HttpHeaders } from '@angular/common/http'; import { Observable } from 'rxjs'; @Injectable({ providedIn: 'root' }) export class ApiService { private apiUrl = 'https://api.example.com/data'; constructor(private http: HttpClient) {} sendData(data: any): Observable<any> { const headers = new HttpHeaders({ 'Content-Type': 'application/json' }); return this.http.post(this.apiUrl, data, { headers }); } } ``` And in my component, I'm calling this service method as follows: ```typescript import { Component } from '@angular/core'; import { ApiService } from './api.service'; @Component({ selector: 'app-my-component', templateUrl: './my-component.component.html' }) export class MyComponent { constructor(private apiService: ApiService) {} submitData() { const payload = { name: 'John', age: 30 }; this.apiService.sendData(payload).subscribe(response => { console.log('Response:', response); }, behavior => { console.behavior('behavior:', behavior); }); } } ``` When I trigger `submitData()`, I receive this behavior from the server: `400 Bad Request: Invalid JSON`. I've tried debugging the request using the browser's developer tools and it shows that the payload is being sent as an empty object `{}`. I've ensured that `JSON.stringify()` is not being called on the payload as it should be handled by Angular's `HttpClient`. I also checked the `Content-Type` header to confirm it's set to `application/json`. Could there be something I'm missing? Are there any specific configurations or scenarios that could lead to this behavior? Any insights would be greatly appreciated! My development environment is Ubuntu. I recently upgraded to Typescript latest. I'd really appreciate any guidance on this.
