I am facing the same problem, did you solve it yet?
The only relevant information I found is https://dev.gnupg.org/T4137

For example, if gpg is used as part of a script executed from a window manager (e.g. passmenu or rofi-pass) the $TERM variable may not be set due to the window manager not being executed from within a shell (e.g. started from a display manager like LightDM). This should still allow us to access the GUI pinentry dialog.

Actually it fails only when you set TERM to the empty string. Unsetting TERM still works:

$ sh
$ gpgconf --kill gpg-agent
$ unset TERM
$ echo | gpg --clearsign

Fixed in master (to be 2.3).

I tried unsetting TERM but that didn't help on my computer. I'm not sure if unsetting TERM in my terminal actually removes it in parcimonie.sh. Setting TERM to xterm manually in the command starting parcimonie also doesn't help.
