Encrypted notebooks do not support this operation

Error message

Encrypted notebooks do not support this operation

What it means

ListDocTree refuses flashcard-filtered listing for encrypted notebooks: with flashcard=true and IsEncryptedBox(boxID) it returns the localized "Encrypted notebooks do not support this operation" (Conf.Language(313)) before reading any card data. Building the flashcard view requires scanning block/deck state across the box, which is not available while content is encrypted.

Solutions

1. Re-issue with flashcard=false (or omit the flag) for encrypted notebooks
2. Point flashcard-filtered views only at non-encrypted notebooks
3. Keep flashcard review flows on non-encrypted notebooks

Example fix

// before: flashcard filter on an encrypted notebook
files, totals, err := model.ListDocTree(encBoxID, "/", sort, true, false, max)

// after: skip the flashcard filter for encrypted notebooks
flashcard := !model.IsEncryptedBox(encBoxID)
files, totals, err = model.ListDocTree(encBoxID, "/", sort, flashcard, false, max)

if flashcard && model.IsEncryptedBox(boxID) {
	flashcard = false // or reject with a clear message
}
files, totals, err := model.ListDocTree(boxID, p, sortMode, flashcard, showHidden, max)

When it happens

Trigger: POST /api/filetree/listDocsByPath or /api/filetree/listDocTree with {"notebook":"<encrypted-box>","flashcard":true}.

Common situations: A plugin or view that always requests flashcard=true regardless of notebook type; switching a notebook to encrypted while a flashcard-filtered doc tree was open.
