There is a REST-service in my Angular 9 to handle all HTTP requests. When I shutdown the REST server there are errors in the console.log() but I'm unable to catch them in the service:
return this.http.post<any[]>(this.path, data, header).pipe(
catchError((err: HttpErrorResponse) => {
console.log("---", err);
return of(null);
})
);
console output is always:
zone-evergreen.js:2845 HEAD https://SERVER/ net::ERR_CERT_COMMON_NAME_INVALID
Why does this happen and why is catchError being ignorred?
