Not getting data from a NodeJs API in Angular?

I am trying to Implement an API in Angular with post request, API is working fine in Postman, but when I Implemented this API in angular data is not posting neither giving me any error, I checked my Network too!

I am getting response in browser

{"code":204,"success":"Client Id is not selected!"}

status code: 200 ok

Payload in Postman:

{"clientid": "D0242"}

Payload showing in my browser:

app.setting

  public static DigestEmailIdPrint = "articles/DigestEmailIdPrint";

service.ts

  DigestEmailIdPrint(clientid) {
return this.http.post<any>(
  this.SERVERURL + this.AppSettings.DigestEmailIdPrint,
  { clientid: clientid }
);
}

app.ts

    ngOnInit(){
      this.DigestEmailIdPrint()   
      }
    DigestEmailIdPrint() {
    var postData = {
      clientid: localStorage.getItem("storageselectedclient"),
    };

    this.article.DigestEmailIdPrint(postData).subscribe(
      (res) => {
        console.log(res);
        console.log("hio");
        if (res.message != "No Record Found") {
          this.DigestEmailIdPrint = res;
        }
      },
      (err) => {
        console.log(err);
      }
    );
  }

>Solution :

Try to update your code to because API is waiting for { clientid: clientid } not {clientid : { clientid: clientid }}

DigestEmailIdPrint(payload) {
  return this.http.post<any>(
  this.SERVERURL + this.AppSettings.DigestEmailIdPrint,
  payload
);
}
