TypeError: Cannot create property 'validator' on string 'abc@gmail.com' at setUpControl

Question

I face issue in formGroup. First Based on URL I take some value and call to API for retrieve particular user-data for pre-field text.

register.html

ERROR TypeError: Cannot create property 'validator' on string 'form'

Once the square brackets added in formGroup (see below), the error disappears
