When entering a page - I get this error and its seems to be some kind of internal appfarm bug.

It came after I set a text input to “auto focus”. When removing it - the problem goes away

Hi Fridtjof,  
To debug this, I would start by finding the place in your app where `pulsate` is being read (this is likely used in a function, action, or service related to this field) – seems like there’s a null check missing.  
Are there any actions triggered `On Focus` or `On Enter` on the field you’re autofocusing?

Hi! We do have a registered bug (crash, with same message) when having an element with autofocus inside a container with “On Click” event! Could this be the case @Fridtjof ?

It should of course not crash (but autofocus inside a clickable container does not sound right either).
