unable to download the csv file in via rest api

Hello,
I'm trying to download the CSV content file using the REST API in Codeigniter 4 but it not working, I'm fetching the data from the database which I need to download via rest API.
In the controller I found this:
return $this->response->download('test.csv', $data); // $data is string

Front in angular:
const headers = new HttpHeaders().append('responseType', 'blob');
this.http.get(path, { headers }).subscribe(
  (res) => {},
  (error) => {console.error(error)}
);

But not working, am I missing something?

Please guide me.

It appears there's an issue with downloading the CSV file via the REST API. Troubleshooting the API call or checking permissions could help resolve this download problem.

Maybe CORS block? See browser console
