I'm using feature form to update attributes and it works fine in 4.16. I started getting an error after moving to 4.17. I can not make sense of the error.
Uncaught (in promise) -- cannot read property 'length' of undefined.
Also, After some time the view becomes unclickable.
Please see the attached image for details
I have a sample in codepen https://codepen.io/markoskifle/pen/PoNzmpm?editors=1000
