Conf.Language(15)

Error message

Conf.Language(15)

What it means

SetBlockReminder cannot find the target block node in the document tree after loading the block's file, so it returns Conf.Language(15): 'Content block with id [%s] not found', interpolated with the offending id. This happens after the subscription check passes, when the id does not resolve to a node (treenode.GetNodeInTree returned nil).

Solutions

1. Verify the id with /api/block/getBlockInfo (or getBlockKramdown) before setting the reminder
2. Fetch a fresh block id via /api/filetree/getDoc or SQL query (/api/query/sql) instead of a cached one
3. Confirm the block still exists in the current workspace/notebook; deleted blocks cannot receive reminders
4. Check the id format: it must be a 14/22-char SiYuan block id without surrounding whitespace

Example fix

// before
await fetchPost('/api/block/setBlockReminder', {id: cachedId, timed});
// after
const info = await fetchSyncPost('/api/block/getBlockInfo', {id: cachedId});
if (info.code !== 0) { showMessage('block ' + cachedId + ' not found'); return; }
await fetchPost('/api/block/setBlockReminder', {id: cachedId, timed});

const info = await fetchSyncPost('/api/block/getBlockInfo', {id});
if (info.code !== 0) throw new Error('block not found: ' + id);

null

try { await setBlockReminder(id, timed); } catch (e) { if (/not found|未找到/.test(String(e))) refreshBlockId(id); else throw e; }

When it happens

Trigger: POST /api/block/setBlockReminder with an id that is not a valid/existing block: malformed id, deleted block, id from another workspace, or a document id whose .sy file failed to load (tree loaded but node nil).

Common situations: Stale ids cached in a plugin after the block was deleted; using a notebook (box) id instead of a block id; automated tests reusing ids from a rebuilt dataset; case-sensitivity or whitespace mistakes when copying ids.
