I am trying to encrypt requset body in angular using Rsa encryption (node-forge) and decrypt it in ASP.NET Core 6

I am trying to encrypt request body in Angular using RSA encryption (node-forge) and decrypt it in ASP.NET Core 6. While decrypting, I can't get the decrypted body only getting [object object ] as output. I have tried to read it using pem reader but that does not work either.

import { Injectable } from '@angular/core';import * as Forge from 'node-forge';@Injectable({  providedIn: 'root',})export class RSA {  publicKey: string =`-----BEGIN PUBLIC KEY-----  MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEArHQ09caWERhxf9deHJr2  AXwBUQuUdmjuZRRTAvkx+VkytEdycTgt8wNR53jjCCSeyK4EeeU04nzoTW6Sqh77  gTK3T9rPy6QPjD7IrFNZeLwwDfy5SFe9G2vzbJ1geyMgSdBAMITOXK9cdAnsCC40  dNfPKly3BCf2SI+6Z3zJXghJZfKa2iucGrpW1Jwnxdwbtf7gzYBwmdu7lCz7o93F  pc3Wd7vCCsjl+PafasuGBPPRhqwuo4fbNuTM6D0oaXWd6Y9HoQ6BanortLotoCXO  WPCJxqyAU52V1H4lgxP8bgYPZFGRrrabgbqsvDivohSxj4xd822LleF7VZD9Gtos  UQIDAQAB  -----END PUBLIC KEY-----`;  constructor() {}  encryptWithPublicKey(valueToEncrypt: string): string {     const scheme={    name: 'RSA-OAEP',    hash:'sha256'  };    const rsa = Forge.pki.publicKeyFromPem(this.publicKey);    const encryptedBytes = rsa.encrypt(valueToEncrypt.toString(),'RSA-OAEP');    return window.btoa(encryptedBytes);  }}

I have tried to convert it into the string but got object object:
