AJAX request not sending expected JSON payload in Angular 12 with HttpClient
I'm prototyping a solution and After trying multiple solutions online, I still can't figure this out... After trying multiple solutions online, I still can't figure this out. I've been struggling with this for a few days now and could really use some help. I'm working with an scenario with making an AJAX request using the HttpClient in Angular 12. My API expects a JSON payload, but it seems that the request is not sending the data correctly. I've tried to log the request body in the network tab, and it appears to be empty. Here's what my code looks like: ```typescript import { HttpClient, HttpHeaders } from '@angular/common/http'; import { Injectable } from '@angular/core'; @Injectable({ providedIn: 'root' }) export class ApiService { private apiUrl = 'https://api.example.com/data'; constructor(private http: HttpClient) {} sendData(data: any) { const headers = new HttpHeaders({ 'Content-Type': 'application/json' }); this.http.post(this.apiUrl, data, { headers }) .subscribe( response => console.log('Response:', response), behavior => console.behavior('behavior:', behavior) ); } } ``` When I call `sendData({ key: 'value' })`, the request payload appears to be missing, and I get a `400 Bad Request` behavior from the server. I've verified that my API is correctly configured to accept JSON and it works with tools like Postman. I've also tried adding the `observe: 'body'` option to the request, but that didn't help. Additionally, I checked that my Angular app's `HttpClientModule` is properly imported in the `AppModule`: ```typescript import { HttpClientModule } from '@angular/common/http'; @NgModule({ declarations: [...], imports: [ BrowserModule, HttpClientModule, ... ], providers: [], bootstrap: [AppComponent] }) export class AppModule { } ``` Has anyone experienced a similar scenario or have any advice on how to debug this further? I feel like I'm missing something simple here, but I've gone through the documentation and need to find what could be wrong. I'm working on a application that needs to handle this. What am I doing wrong? I'm working on a service that needs to handle this. I'm working with Typescript in a Docker container on Linux. My team is using Typescript for this REST API. I'm coming from a different tech stack and learning Typescript. Am I missing something obvious?
