In Strapi, previously we had to use { payload } to post but now we have to use {data { payload } } how do I post using Angular anyone could help plzzz

Question

This is my service.ts file

 addOrder(data:Order):Observable<any> {
            let API_URL=`${strapiendpoint}/orders`;
            return this.http.post(API_URL,data,httpOptions)
              .pipe(
                catchError(this.errorMgmt)
              )
          }
   

This is my component.ts file where I am posting the data through service

    createOrder() {
            this.strapiService.addOrder(this.form.value)
                .pipe(first())
                .subscribe({
                    next: () => {
                        this.alertService.success('Order added successfully');
                     },
                    error: error => {
                      this.loading = false;
                    }
                });
        }
