Or Is there any other way for server side rendering baside (angular universal) for SEO

tomastrajan commented 4 years ago

Hi @nobaddy !

The error seems to be with some object which is missing where we try to access some value on it,

the code in question can be made more robust by using if () or even new obj?.prop, besides that, you might need to provide some default values for these properties for it to make sense, as settings may decide language, theme etc... which will then need to be used during SSR so you propabbly have to go with some defaults. (as settings are then stored during runtime in browser local storage which is not available on the server)

Hope that helps!

Cheers
