from_email not substituted from filed

[kaolpr]

I have the following configuration in my form configuration:

from_name: name
from_email: email_address

I expect from_name and from_email to be substituted with value from name and email_address fields defined for the form:

fields:
        name:
            type: text
            options:
                required: true
                label: Name and surname
                attr:
                    placeholder: Place your name here...
                constraints: [ NotBlank ]

        email_address:
            type: email
            options:
                required: true
                label: E-mail address
                attr:
                    placeholder: Your e-mail address
                constraints: [ NotBlank, Email ]

However, it seems not to happen as on submission I'm receiving 500 error: An exception has been thrown during the rendering of a template ("Email "email_address" does not comply with addr-spec of RFC 2822."). It looks that email_address is treated as a string literal rather than field name.
