Error message

Invalid district

What it means

An `InvalidParameterError` at lib/routes/wellcee/rent.tsx:70 when the optional `:district` path parameter is provided but does not match any `name` in the district list returned by `getDistricts(cityInfo.id)` for the given city. Only evaluated when `district` is non-empty. Districts are Chinese-language names fetched dynamically per-city.

Solutions

1. Omit the `:district` parameter entirely to get all listings for the city.
2. Inspect the Wellcee website for the target city to find the exact Chinese district name used internally.
3. Verify getDistricts() in ./utils still returns the expected `[{ name, id, ... }]` shape.

const districts = await getDistricts(cityInfo.id);
const validDistrictNames = districts.map((d) => d.name);
if (district && !validDistrictNames.includes(district)) {
    throw new InvalidParameterError(`Invalid district. Supported: ${validDistrictNames.join(', ')}`);
}

const isValidWellceeDistrict = (district: string, districts: Array<{ name: string }>): boolean =>
    districts.some((d) => d.name === district);

When it happens

Trigger: Passing a valid city but a district that doesn't belong to it (e.g. a Beijing district under 上海); passing the English district name; the district was renamed in Wellcee's database; URL-encoding issues with Chinese characters in the path.

Common situations: User enters English district name; user mixes up which districts belong to which city; district list API shape changed.
