The form has ceased to correct

Hello. When you fill out the form, a process is also created in the status of "NC Application". At this stage, there is an action to fill in the field, where as an email contact is written
[name_first_ru].[name_last_ru]@{|$customuser_Domen|}
if at least one value from the specified variables is missing, an invalid email will be created and an error will be generated when trying to write it to the contact card.
You can turn off the action "Fill the field to the process or contact" and then the form will not give this error
