Error message

eastmoney returned no money-flow data

What it means

The eastmoney money-flow CLI throws CliError('NO_DATA') when the endpoint returns HTTP 200 but `data.data.diff` is absent or empty — i.e. the API succeeded structurally but returned no capital-flow rows. This separates 'upstream returned nothing' from transport errors and from invalid-argument errors, and unlike error 1356 its message is static (no parameters interpolated).

Solutions

1. Check whether the current date is a Chinese trading day — flow rankings are empty outside trading sessions.
2. Verify the range argument maps to a valid RANGES fid (INVALID_ARGUMENT would have fired otherwise, but a wrong-but-accepted key can yield empty payloads).
3. Log or curl the raw response body and inspect data.data to see whether the envelope changed or is genuinely empty.
4. If the envelope changed, update the extraction path `data?.data?.diff` to match the current schema.
5. Retry during market hours or shortly after close when flow data is populated.

Example fix

// before
const diff = Array.isArray(data?.data?.diff) ? data.data.diff : [];
if (diff.length === 0) throw new CliError('NO_DATA', 'eastmoney returned no money-flow data');
// after — surface the envelope shape to aid diagnosis
const diff = Array.isArray(data?.data?.diff) ? data.data.diff : [];
if (diff.length === 0) {
  console.error('money-flow envelope keys:', Object.keys(data ?? {}), 'data:', JSON.stringify(data?.data)?.slice(0, 200));
  throw new CliError('NO_DATA', 'eastmoney returned no money-flow data');
}

// Only expect data during/after trading sessions on weekdays
const now = new Date();
const day = now.getUTCDay();
const utc8Hour = (now.getUTCHours() + 8) % 24;
if (day === 0 || day === 6 || utc8Hour < 10) console.warn('Market likely closed or pre-open; empty money-flow data is likely');

function hasDiff(data) { return Array.isArray(data?.data?.diff) && data.data.diff.length > 0; }

try {
  const rows = await runMoneyFlow({ range });
} catch (err) {
  if (err instanceof CliError && err.code === 'NO_DATA') {
    console.warn('No money-flow rows (market closed or schema change); using last cached snapshot');
    return readCachedSnapshot();
  }
  throw err;
}

When it happens

Trigger: Querying when `data.data.diff` is missing: a non-trading day/period where no A-share flow ranking exists, eastmoney returning a success envelope with a null data object (e.g. {data:null} for an unrecognized fs/fid combination), or an API schema change renaming the diff array.

Common situations: Running on weekends or Chinese market holidays; a request whose fid (from the range argument) or fs market filter no longer matches what the API accepts, yielding a silent empty payload; eastmoney quietly changing the JSON envelope so diff moves elsewhere; off-hours runs before flow data is computed.
