org-capture template with file local variables

Question

I'm trying to set up a capture that automatically deactivates the undo-tree history saving in an encrypted file by setting file local variables. When I call the capture and have entered the filename the following error happens:

error("Capture template `%s': %s" "E" "Template is not a valid Org entry or tree")

(setq org-capture-templates
      '(("E" "Encrypted File" entry (file my-org-capture-ask-for-filename)
                                 "-*- undo-tree-auto-save-history: nil; epa-file-encrypt-to: nil; -*-

* %i%?")))

The error disappears once I remove the file variables:

(setq org-capture-templates
      '(("E" "Encrypted File" entry (file my-org-capture-ask-for-filename)
                                 "* %i%?")))

Do I have to escape the file variable line somehow?

Answer 1

Okay, I figured it out. I had to specify "plain" instead of "entry" as type, otherwise org-capture expects an org mode node, with a headline:

(setq org-capture-templates
      '(("E" "Encrypted File" plain (file my-org-capture-ask-for-filename)
                                 "-*- undo-tree-auto-save-history: nil; epa-file-encrypt-to: nil; -*-

* %i%?")))
