On form submit, a download button is displayed to the user and an email to which the pdf is attached is sent to the user.
I have set the value of field  to the entry ID via the Embedded Forms setting.
The downloaded version of the pdf shows the value of field  to be equal to the entity ID.
The emailed version of the pdf shows the value of field  to be NOTSET.
Since I have used this entire system, PDF, field map, settings, and all, for the last three years, I’m pretty certain that this used to work. What might I be doing wrong? How do I insert the entry ID into the required field?
