Error message

Bad category. See <a href="https://docs.rsshub.app/routes/government#深圳市罗湖区人民政府">docs</a>

What it means

Thrown as an InvalidParameterError by the Shenzhen Luohu district government route when the ':caty' path parameter is not a key in the config object. Currently only one category is defined: 'tzgg' (通知公告 / Notice Announcements). The check is 'if (!cfg)' where cfg = config[ctx.req.param('caty')].

Solutions

  1. Use the only valid category: /gov/shenzhen/szlh/zwfw/zffw/tzgg
  2. Check the route description table which shows only one option (tzgg)
  3. If you need other Luohu district categories, they may not be supported yet — consider contributing a new config entry

Example fix

// No code fix needed — the error message already links to docs.
// The only valid value is 'tzgg'. Use:
//   /gov/shenzhen/szlh/zwfw/zffw/tzgg
Defensive patterns

Strategy: validation

Validate before calling

const VALID_CATEGORIES = ['tzgg']; // only one supported
const caty = ctx.req.param('caty');
if (!VALID_CATEGORIES.includes(caty)) {
    throw new InvalidParameterError(`Bad category '${caty}'. Only 'tzgg' is supported.`);
}

Type guard

function isValidSzlhCategory(caty: string): caty is 'tzgg' {
    return caty === 'tzgg';
}

Prevention

When it happens

Trigger: A request to /gov/shenzhen/szlh/zwfw/zffw/:caty where caty is anything other than 'tzgg'. Since there is only one valid value, any other input — including common government category codes like 'zfcg' or 'zjxx' — will trigger this error.

Common situations: Assuming more categories exist than actually do (the route only supports tzgg); using category codes from other Shenzhen government routes that have more options; typo in 'tzgg'.
