FirebaseError有一个"代码"属性,但是如何在promise的catch方法中读取它？以下引发TypeScript错误:Property 'code' does not exist on type 'Error'.

this.af.database
.object(`/some/path`)
.set(newObj)
.then(data => {
  console.log('success');
})
.catch(err => {
  // Property 'code' does not exist on type 'Error'.
  console.log(`code`, err.code);
});
