My page is quite complex so I can't give you a simple repro test case right now, but maybe there is no need as the bug seems to be the function _isLatLngBoundsLiteral that seems optimistic by not testing undefined/null prior to use it.

Ok,

I had a [fitBounds]="latLngBounds" which was now not-working because of the new breaking change API of
#1389

@jscti thanks for the report. The type guard is wrong here, it has to check if the value is undefined/null before checking the method. I will provide a fix for it asap
