Angular Object, value not found

Hi every one, I have a problem for getting Text of an email field on a prod Environment coded with Angular.
On Validation, I just have to make a Verification or a get on -> ‘ng-reflect-model’ Object.
But on prod, this attribute isn’t showed in the HTML but I have the value correctly displayed in the field.
I have seen a similar topic problem and it was resolved by using a get attribute. But even when I’m Trying with a get attribute I have a NULL value displayed with a println.

I have no problem to localise with xpath the Web Object.
Does anyone have had this problem on solved it?

validation no_text_attribute

Thanks in advance!
