Hi everyone, I am fairly new to org mode and am trying out encrypting sections of an org file using org-encrypt-entry.

Setting org-crypt-key to nil as mentioned in the org-mode website allows symmetric encryption but when I provide a GPG key and try to encrypt the text under the heading, I get the below error -

Wrong type argument: stringp, stringp

Can anyone have a look and point out what I might be doing wrong ?
