Error message

From date cannot be after To date

What it means

Thrown by POST /api/v1/rooms.export with type 'file' when convertedDateFrom is greater than convertedDateTo. dateFrom defaults to epoch 0 and dateTo defaults to now, and the server adds one day to dateTo before comparing, so the error only fires when the caller explicitly sends an inverted or overlapping range.

Solutions

1. Validate and swap/reject the range client-side before sending
2. Check the field wiring: dateFrom is the older bound, dateTo the newer
3. Rely on defaults (omit both) when exporting the full history

Example fix

// before
await sdk.post('rooms.export', { rid, type: 'file', dateFrom: '2026-08-18', dateTo: '2026-08-01' }); // inverted

// after
let [from, to] = [new Date(dateFrom), new Date(dateTo)].sort((a, b) => a - b);
await sdk.post('rooms.export', { rid, type: 'file', dateFrom: from.toISOString(), dateTo: to.toISOString() });

const from = new Date(dateFrom ?? 0);
const to = new Date(dateTo ?? Date.now());
if (from > to) [dateFrom, dateTo] = [dateTo, dateFrom]; // or reject with a form error

try {
  await sdk.post('rooms.export', { rid, type: 'file', dateFrom, dateTo });
} catch (e: any) {
  if (e?.response?.data?.errorType === 'error-invalid-dates') {
    throw new Error('export range inverted — fix dateFrom/dateTo order');
  }
  throw e;
}

When it happens

Trigger: POST rooms.export with dateFrom later than dateTo (e.g. from 2026-08-18, to 2026-08-01); date pickers submitting end-before-start; timezone conversion flipping the order across midnight.

Common situations: UIs with two independent date inputs and no ordering validation; reports where 'from' and 'to' fields are wired in reverse; DST or timezone shifts reordering same-day ranges; copy-pasted ranges from other tools.
