First you have see on your back-end may be CORS error are there, if CORS is enable, disable it and then try it. also try with this code.


 httpOptions = { headers: new HttpHeaders({'Content-Type': 'application/json', 'Authorization': 'Bearer '  'token'}) };
    constructor(private httpClient: HttpClient) { };
    getData(): Observable<string> {
        return this.httpClient.post<string>(Constant.BASE_URL   "UserReaction/deleteUserReaction", { "data": { 'userReactionId': 'userReactionId' } }, this.httpOptions).pipe(retry(3), catchError(Constant.handleError));
    }
