我已将 MetaMask 与 Angular 集成，在从代码中打开 MetaMask 扩展时出现此错误。

以下是我打开扩展的代码。我在单击打开 MetaMask 时调用此函数，它给出了该错误

MetaMask - RPC 错误：权限请求已挂起；请稍等。{code:-32002, message:“权限请求已待处理；请稍候。”}

ethEnabled(template?): any
  {
    if ((window as any).web3)
    {
      (window as any).web3 = new Web3((window as any).web3.currentProvider);
      (window as any).ethereum.enable();
      console.log((window as any).ethereum.enable());

    }
    else
    {
      this.modalRef = this.modalService.show(template);
    }
  }

我有一个名为HomeService的服务 ,在该服务中,我正在设置并获取一些工作正常的数据.这是我服务的代码.

import { Injectable } from '@angular/core';

@Injectable()
export class HomeService {

name:string;

constructor() { }

setParams(val) {
      this.name = val;
}
getParams() {
    return this.name;
}

}

我在组件A中设置params 并将其放入组件B中.我想要的是继续观察getParams()以便在第二个组件中进行更改.我在组件A中得到params值,我在其中设置它,但我无法在组件B中获得这些值.组件B中的意思是不注意变化.

I have tried many online solution but none of them worked. My issue is that when I change anything in the file, browser is not reloading the page. Below are the configs of my project
