No NotebookLM sources were found on the current page.

Error message

No NotebookLM sources were found on the current page.

What it means

opencli notebooklm source-guide throws this EmptyResultError when a notebook is open but the combined RPC + DOM listing found zero sources, so there is nothing to match the --source query against. Thrown before any guide generation is attempted.

Solutions

1. Add sources to the notebook via `opencli notebooklm add-source` or the web UI.
2. Reopen the notebook (`opencli notebooklm open <notebook>`) and retry after the source list renders.
3. Retry later or update opencli if NotebookLM's UI changed and both listing strategies fail.

Example fix

// before
opencli notebooklm source-guide --source "faq"   # notebook has no sources
// after
opencli notebooklm add-source "faq.md"
opencli notebooklm source-guide --source "faq"

const sources = await exec('opencli notebooklm source-list --json');
if (!Array.isArray(sources) || sources.length === 0) throw new Error('Notebook empty or sources not loaded; add a source or reopen');

function hasSources(rows) {
  return Array.isArray(rows) && rows.length > 0 && typeof rows[0]?.id === 'string';
}

try {
  return await run('opencli notebooklm source-guide', ['--source', name]);
} catch (err) {
  if (/No NotebookLM sources were found/.test(err.message)) {
    await run('opencli notebooklm open', [notebook]);
    await delay(2000);
    return run('opencli notebooklm source-guide', ['--source', name]);
  }
  throw err;
}

When it happens

Trigger: source-guide called against an empty notebook, or when listNotebooklmSourcesViaRpc fails (caught to []) and listNotebooklmSourcesFromPage finds no rows, e.g. during page load or after a NotebookLM UI change.

Common situations: New notebook with no sources uploaded yet; slow render timing causing both strategies to see nothing; adapter selectors broken after a NotebookLM frontend update.
