What could be the reason for receiving an HttpErrorResponse when making a GET request that returns byte data

When using these headers, the API returns byte data as a response.

let headers = {
      headers: new HttpHeaders({
        'Content-Type': 'application/octet-stream',
        'responseType':'arraybuffer' as 'json',
        'uid':uid
      })
    };

The API request is returning byte data.

this.http.get(url,headers)
    .pipe(map((res)=>{
      console.log(res)  
      return res;
    }),err=>{
      console.log(err)  //receiving HttpErrorResponse
      return err;
    }

Answer №1

After removing the responseType HttpHeaders and directly placing them in the headers object, it successfully resolved the issue for me.

const updatedHeaders = {
      headers: new HttpHeaders({
        'Content-Type': 'application/octet-stream',
        'uid': uid
      }),
      'responseType': 'arraybuffer' as 'json',
    };
