Does someone know how to solve it? Or what is causing this error? The only thing that I know explain is that this error occurs after return this.http.get<string>(url, { headers: headers }).toPromise();
and before .then(...
as usual. This code runs fine for the first time, after close the current Page, and reopening it after, is when it occurs.
