Conf.Language(313)

Error message

Conf.Language(313)

What it means

Doc2Heading merges content of the source tree into a tree in another notebook. For encrypted notebooks each notebook has its own DEK (data encryption key); merging across two different notebooks would write content encrypted under the wrong key and corrupt data. The kernel therefore rejects any src/target pair that is not within the same crypto boundary with Conf.Language(313) ('Encrypted notebooks do not support this operation').

Solutions

  1. Move the document within the same notebook, or convert to heading only when both source and target are in the same notebook
  2. Decrypt (remove encryption from) the notebooks involved if cross-notebook merging is genuinely needed
  3. Create a copy of content manually instead of using the merge transaction
Defensive patterns

Strategy: validation

Validate before calling

const boxes = new Set([srcBoxID, targetBoxID]);
// only merge within the same notebook (or same crypto boundary)
if (srcBoxID !== targetBoxID) throw new Error('cross-notebook merge not allowed for encrypted notebooks');

Try / catch

try {
  await fetchPost('/api/filetree/doc2Heading', {srcID, targetID});
} catch (e) {
  if (String(e.msg).includes('do not support this operation')) {
    // fall back to moving the document instead of merging
  } else throw e;
}

Prevention

When it happens

Trigger: Calling Doc2Heading where srcTree.Box and targetTree.Box are different notebooks and at least one (or the pair) crosses an encrypted-notebook boundary, i.e. IsSameCryptoBoundary(srcBox, targetBox) is false.

Common situations: Drag-dropping a doc from an encrypted notebook onto a heading in a normal notebook (or between two different encrypted notebooks); automation that moves docs between notebooks.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
