Console log Undefined

Question

console log undefined here

      this.http.get(this.rootURL + "/Report/"+id)
      .toPromise().then(res => this.report = res as Report);
      console.log(this.report);
  }

here console log the data

      this.http.get(this.rootURL + "/Report/"+id)
      .toPromise().then(res => console.log(res));
      console.log(this.report);
  }

what can I do to assign result to Result Object

You need to perform your other operations inside the `then` callback, or use async/await. — , Apr 20 '19 at 11:50

Log your data within the then of your promise:

this.http.get(this.rootURL + "/Report/"+id)
  .toPromise()
  .then(res => {
    // Promise gets fulfilled and its response can be assigned
    this.report = res as Report;
    console.log(this.report);

    // Perform other actions
    // ...
  })
  .catch(reason => {
    // Something went wrong, your promise gets rejected
    console.log(reason);
  });

are you using await?

you should be doing something like this:

const main = async () => {
await this.http.get(this.rootURL + "/Report/"+id).toPromise().then(data => {
console.log(data);
})
}
