Angular 8 - CORS error using HTTP to download file from Firebase Storage

Question

I am trying to download the contents of a video file from Firebase Storage using Angular 8's HTTP Client.

Given the URL for the file in Firebase Storage, the following code is used to download its contents:

  public downloadVideo = (url: string): Observable<any> => {
    return this.http.get(url,
      {
        responseType: 'arraybuffer',
      }
    );
  };
}

The following error is received:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at [url for resource] (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 200.

I tried the answer at Firebase Storage and Access-Control-Allow-Origin

But, it did not resolve the issue.

Any ideas?

Thanks in advance
