Console Error in the frame before TextInput

I'm converting and old FL game in HTML5 + JS
In a frame of a subclip timeline the user shound input his name in a TextInput component.
Well, if the component is on the stage, in the previous frame I get an error:

Uncaught TypeError: Cannot read property 'css' of null
at String.<anonymous> (anwidget.js?1596554221158:171)
at Function.each (jquery-2.2.4.min.js?1596554221158:2)

at lib.an_TextInput._handleDrawEnd (avatar_maker.js?1596554221293:14572)
at createjs-2015.11.26.min.js:12

If I delete the component, in the same frame (the previos of where it should be the input) I don't have any console error.

I tried to delete TI from lib and place a new one, I tried to put one TI on frame 1. No success 😞
Any clue to solve this?
