Failed to fetch documents from Paperless-ngx: ${res.status}

Error message

Failed to fetch documents from Paperless-ngx: ${res.status}

What it means

PaperlessNgxLoader.fetchAllDocuments throws (inside a per-page try) when the documents list endpoint returns non-ok. The inner try/catch logs and breaks the pagination loop rather than propagating, so a failed page stops further fetching but does not crash the call.

Solutions

1. Confirm the token: `curl -H "Authorization: Token <token>" <baseUrl>/api/documents/`.
2. Verify baseUrl.origin is correct (the constructor strips to origin).
3. Check the logged status code in the per-page error.
4. Ensure the token has document read permissions.

Example fix

// before
if (!res.ok) throw new Error(`Failed to fetch documents from Paperless-ngx: ${res.status}`);

// after — include status text + the page being fetched
if (!res.ok) throw new Error(`Paperless-ngx ${res.status} ${res.statusText} on page ${page} (${nextUrl})`);

async function paperlessAuthOk(baseUrl, token) {
  const r = await fetch(`${new URL(baseUrl).origin}/api/documents/?page_size=1`, {
    headers: { Authorization: `Token ${token}` },
  });
  return r.ok;
}

// fetchAllDocuments swallows per-page errors and breaks the loop
const docs = await loader.fetchAllDocuments();
if (docs.length === 0) { /* check logs for "Failed to fetch documents from Paperless-ngx: <status>" */ }

When it happens

Trigger: GET /api/documents/ returns non-2xx: 401 (bad apiToken — note the "Token <token>" scheme, not Bearer), 403, 404 (wrong baseUrl), 5xx.

Common situations: Wrong apiToken; baseUrl pointing to the wrong origin (the constructor strips to origin); Paperless-ngx API path changed; token lacks read permissions.
