Error message

Invalid city

What it means

An `InvalidParameterError` at lib/routes/wellcee/rent.tsx:62 when the `:city` path parameter does not match any `chCityName` in the list fetched by `getCitys()`. Wellcee's city list contains Chinese-language city names (e.g. 北京, 上海), so the match is exact string equality against Chinese names. The supported set is discoverable via the `/wellcee/support-city` route.

Solutions

1. Call the `/wellcee/support-city` route first to see the exact supported Chinese city names.
2. Use the exact `chCityName` value (Chinese characters) as the `:city` path segment.
3. If no cities match at all, check whether the getCitys() utility in ./utils still hits a valid Wellcee API endpoint.

const citys = await getCitys();
const validCityNames = citys.map((c) => c.chCityName);
if (!validCityNames.includes(city)) {
    throw new InvalidParameterError(`Invalid city. Supported: ${validCityNames.join(', ')}`);
}

const isValidWellceeCity = (city: string, citys: Array<{ chCityName: string }>): boolean =>
    citys.some((c) => c.chCityName === city);

When it happens

Trigger: Passing 'Beijing' instead of '北京'; passing a city Wellcee does not operate in; trailing whitespace or URL-encoding in the city parameter; the getCitys() API changed and returns an unexpected shape so the find always fails.

Common situations: User enters the English city name; user guesses a city not in Wellcee's coverage; the support-city list changed.
