Cannot read properties of null (reading 'dontFocus')

Asked by Santiago Losada Borrajo

We have encountered this error but we couldn't find out what is the reason why it doesn't show the error in the browser console. You suppose that we are missing some parameter but we don't know which one.

It looks like you are passing "null" as the "options" argument. Try removing it or use an empty object - "{}".

This problem should be fixed now in the latest sandbox build (2023.1.5527).

It looks like in Angular this happens if you use the "date" attribute of <DayPilotNavigator>.

Anyway, that should be fixed now so I recommend trying the latest sandbox build. Please let me know if the problem persists.
