Data source ID not found

Error message

Data source ID not found

What it means

Thrown by the NEA (National Energy Administration) bureau route when the HTML element 'ul#showData0' either doesn't exist or has no 'data' attribute, or the data attribute doesn't contain a colon-separated value with an ID at the end. The route parses this data attribute (e.g., 'something:12345') to construct a JSON data source URL (ds_12345.json).

Solutions

1. Open https://www.nea.gov.cn/sjzz/{bureau}/index.htm in a browser and inspect ul#showData0 to verify the data attribute still exists
2. If the data source mechanism changed, reverse-engineer the new data-loading approach (check network requests in DevTools)
3. Update the selector or data-attribute parsing logic to match the new page structure
4. Verify the bureau code is valid using the options listed in the route parameters

Example fix

// before
const dataSourceId: string | undefined = $('ul#showData0').attr('data')?.split(/:/).pop();
if (!dataSourceId) {
    throw new Error('Data source ID not found');
}

// after (more defensive parsing with diagnostic)
const dataAttr = $('ul#showData0').attr('data');
const dataSourceId = dataAttr?.split(/:/).pop();
if (!dataSourceId) {
    throw new Error(`Data source ID not found on ${link}. The page structure may have changed. ul#showData0 data attribute: ${dataAttr}`);
}

// Wrap data-source extraction in try-catch with a meaningful fallback
let dataSourceId: string | undefined;
try {
    dataSourceId = $('ul#showData0').attr('data')?.split(/:/).pop();
} catch {
    // selector or attribute missing
}
if (!dataSourceId) {
    // Fall back to parsing the page differently, or return allowEmpty
    return { title: $('title').text(), link, item: [], allowEmpty: true };
}

When it happens

Trigger: A GET to https://www.nea.gov.cn/sjzz/{bureau}/index.htm returns HTML where ul#showData0 is missing, has no data attribute, or the data attribute format changed. The split(/:/).pop() returns undefined when the data attribute is empty or contains no colon.

Common situations: The NEA website was redesigned and the data-loading mechanism changed (e.g., switched from JSON data sources to server-side rendering); the specific bureau page uses a different HTML structure; the bureau code is valid but the page is a redirect or error page.
