Error during upload of ${fileName} create table: ${createTab

Error message

Error during upload of ${fileName} create table: ${createTableSqlWithoutLocation}: ${error.error}

What it means

During stream import, temp files are POSTed to Cube Store's /upload-temp-file endpoint. If the server responds with non-200, the driver reads the JSON error body and throws this message including the file name and the CREATE TABLE SQL, surfacing the Cube Store-side error.

Solutions

Check Cube Store logs for the underlying `error` in the response body.
Verify CUBEJS_CUBESTORE_HOST/PORT and that Cube Store is running/reachable.
Restart the pre-aggregation build and confirm disk space on the Cube Store host.
Align Cube Store and cube.js versions (cubestore upgrade).

Defensive patterns

Strategy: retry

Validate before calling

// check Cube Store reachability before heavy builds
const res = await fetch(`http://${cubestoreHost}:${cubestorePort}/v1/status`);
if (!res.ok) throw new Error('Cube Store is not reachable before pre-aggregation upload');

Try / catch

try {
  await driver.uploadTable(table, columns, tableData);
} catch (e) {
  if (e.message.startsWith('Error during upload of')) {
    console.error('Cube Store rejected temp-file upload; check Cube Store logs and disk space');
    await retryWithBackoff(() => driver.uploadTable(table, columns, tableData), 3);
  }
  throw e;
}

Prevention

Monitor Cube Store process health and disk space.
Verify CUBEJS_CUBESTORE_HOST/PORT and auth token settings.
Keep Cube Store and cube.js versions in sync.
Add retries with backoff for transient network failures during builds.

When it happens

Trigger: POST to ${baseUrl}/upload-temp-file?name=... returns status != 200 — Cube Store unreachable/misconfigured, disk full on Cube Store side, rejected file name, or HTTP/WS proxy misrouting (baseUrl ws->http rewrite failing).

Common situations: Cube Store process down or restarted during pre-aggregation build; wrong CUBEJS_CUBESTORE_HOST/PORT; Cube Store version mismatch rejecting the request; network/firewall issues; auth token mismatch between cube.js and Cube Store.
