Server error

Error message

Server error

What it means

Thrown in documentLibrary.js's batch importer when creating a CSV document per spreadsheet sheet via POST /api/document returns non-2xx. The generic 'Server error' discards status and body; because this is inside a per-file loop, the failure aborts remaining sheets of that workbook and increments the failed counter shown in the summary.

Solutions

1. Reproduce with a single-sheet small xlsx to separate size/auth causes.
2. Add credentials: 'same-origin' to these POST /api/document calls to match the rest of the app.
3. Raise the JSON body limit if large sheets are expected.
4. Include status/detail in the message instead of 'Server error'.

Example fix

// before
const res = await fetch(`${API_BASE}/api/document`, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ title: sheetTitle, language: 'csv', content: csv }),
});
if (!res.ok) throw new Error('Server error');

// after
const res = await fetch(`${API_BASE}/api/document`, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  credentials: 'same-origin',
  body: JSON.stringify({ title: sheetTitle, language: 'csv', content: csv }),
});
if (!res.ok) {
  let detail = '';
  try { const j = await res.json(); detail = j?.detail || j?.error || ''; } catch (_) {}
  throw new Error(`Sheet import failed (${sheetTitle}): HTTP ${res.status}${detail ? ` — ${detail}` : ''}`);
}

if (!csv.trim()) continue; // skip empty sheets before hitting the API
if (csv.length > CSV_MAX_CHARS) { csv = csv.slice(0, CSV_MAX_CHARS); }

const res = await fetch(`${API_BASE}/api/document`, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  credentials: 'same-origin',
  body: JSON.stringify({ title: sheetTitle, language: 'csv', content: csv }),
});
if (!res.ok) {
  let detail = '';
  try { const j = await res.json(); detail = j?.detail || ''; } catch (_) {}
  throw new Error(`Sheet '${sheetTitle}' import failed: HTTP ${res.status}${detail ? ' — ' + detail : ''}`);
}

When it happens

Trigger: Sheet-to-CSV conversion succeeded but the create call rejects: content too large (413 — big sheets make huge JSON), schema validation on {title, language:'csv', content} (422), missing credentials note — these creates omit credentials: 'same-origin' unlike elsewhere — or genuine 500s.

Common situations: Importing multi-MB xlsx workbooks whose CSV expansion exceeds request limits; auth-requiring deployments where the omitted credentials cause 401; title with characters a strict backend rejects.
