Hi guys.
I'm trying to test a route resolver and everything seems to be working fine for the successful resolve, but for unsuccessful resolves, I redirect the user to a different route using

            return from(
                this.router.navigate(['app/maintenance'], { state: { tab } 

when cs2pr completes and no errors/warnings have to be emitted, the screen stays empty.

as a user I dont know whether everything worked well and nothing had to be reported or there was a error and I dont see it.

at best we could emit a processed x errors and y warnings or similar status message at the very end into STDERR, so we dont destory possible consumers of our gihtub-api checks
