Conf.Language(390)

Error message

Conf.Language(390)

What it means

setNodeAttrs0 rejects setting the 'bookmark' or 'tags' attribute (case-insensitive) on a block inside an encrypted notebook, returning Conf.Language(390): 'Encrypted notebooks do not support bookmarks and tags, please remove the %s attribute of this block first'. Encrypted notebooks are isolated islands without the global SQLite aggregation these attributes depend on.

Solutions

  1. Remove the 'bookmark'/'tags' keys from the attribute map before calling when the target box is encrypted
  2. Keep bookmark/tag workflows out of encrypted notebooks; use unencrypted notebooks for those blocks
  3. Partition your batch by notebook: apply full attrs to normal notebooks, filtered attrs to encrypted ones
  4. Check the box type first (e.g. via workspace notebook list / IsEncryptedBox semantics) and warn the user instead of failing

Example fix

// before
await fetchPost('/api/attr/setBlockAttrs', {id, attrs: {bookmark: 'b', custom: 'x'}});
// after
if (isEncryptedBox(boxOf(id))) delete attrs.bookmark, delete attrs.tags;
await fetchPost('/api/attr/setBlockAttrs', {id, attrs});
Defensive patterns

Strategy: validation

Validate before calling

const FORBIDDEN = ['bookmark', 'tags'];
for (const k of Object.keys(attrs)) {
  if (FORBIDDEN.includes(k.toLowerCase()) && isEncryptedBox(boxId)) delete attrs[k];
}

Type guard

null

Try / catch

try { await setBlockAttrs(id, attrs); } catch (e) { if (/bookmark|tags/.test(String(e))) { delete forbiddenKeys(attrs); await setBlockAttrs(id, attrs); } else throw e; }

Prevention

When it happens

Trigger: POST /api/attr/setBlockAttrs (also batchSetBlockAttrs, setNodeAttrs with tx, or any path like updateBoundBlockAvsAttribute / doRemoveAttrViewView that funnels into setNodeAttrs0) with nameValues containing key 'bookmark' or 'tags' (any casing) while the block's box is an encrypted box (IsBoxEncrypted(boxID)).

Common situations: Plugin or script bulk-setting custom+standard attributes across all notebooks, some encrypted; drag/drop or sync flows copying attrs into encrypted notebooks; attribute-view bound blocks trying to write tags.

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.
