The dynamic form field, which uses a template in the layout's rule set, is not assigning the value.

I am creating a new data entry form using a dynamic form based on a custom object. In some fields, I have applied templates - some for calculating values in other fields and some for fetching related field values based on a selected dropdown option.

However, when I attempt to submit the data, the fields that use templates in the layout's rule set are showing undefined values.

How can I pass values from the layout template to the dynamic form?
