NO_DATA

Error message

eastmoney returned no sector data

What it means

After a successful sectors API response, the CLI requires data.data.diff to be a non-empty array. An empty or missing diff means eastmoney returned no sector data for the requested type/sort, so CliError NO_DATA is thrown.

Solutions

1. Verify the --type value is a supported sector type and try the default
2. Try a different sort key to see if other queries return data
3. Call the endpoint directly with curl and the same fs/fid params to inspect the raw payload
4. Update the CLI if the eastmoney response schema changed

Example fix

// before
sectors({ type: 'concept', sort: 'main' }); // returns empty for this combo
// after
sectors({ type: 'industry', sort: 'change' });

const KNOWN_TYPES = ['industry','concept'];
if (args.type && !KNOWN_TYPES.includes(String(args.type).toLowerCase())) throw new Error('unsupported sector type');

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

try {
  const rows = await sectors({ type, sort });
} catch (e) {
  if (e.code === 'NO_DATA') console.warn('eastmoney returned no sector data; try a different type/sort');
  else throw e;
}

When it happens

Trigger: Requesting a sector type/fs whose result list is empty (e.g. an unsupported or deprecated fs value), eastmoney returning data:null for the query, or a schema change moving the diff field.

Common situations: eastmoney silently returning empty payloads for some fs values, invalid --type combinations that pass local validation but match nothing server-side, API contract drift after an eastmoney update.
