Invalid date format. Expected YYYYMMDD, for example `2026031

Error message

Invalid date format. Expected YYYYMMDD, for example `20260316`. 

What it means

Thrown by the Fjdaily (Fujian Daily) route's `getIssueDate` function when the user-supplied `date` parameter does not match the regex `/^\d{8}$/`. The route expects exactly 8 digits in YYYYMMDD format (e.g., `20260316`). This is pre-flight validation before any network request is made.

Solutions

1. Format the date as exactly 8 digits: YYYYMMDD, e.g., `/fjdaily/20260316`.
2. Remove all separators (dashes, slashes) from the date string.
3. Omit the date parameter entirely to fetch the latest edition automatically.

function validateDateString(date: string | undefined): { yearMonth: string; day: string } {
    if (!date) throw new Error('Date is required');
    if (!/^\d{8}$/.test(date)) {
        throw new Error('Invalid date format. Expected YYYYMMDD, e.g., 20260316');
    }
    return { yearMonth: date.slice(0, 6), day: date.slice(6, 8) };
}

function isValidYYYYMMDD(date: string): boolean {
    if (!/^\d{8}$/.test(date)) return false;
    const year = parseInt(date.slice(0, 4));
    const month = parseInt(date.slice(4, 6));
    const day = parseInt(date.slice(6, 8));
    return year >= 1900 && month >= 1 && month <= 12 && day >= 1 && day <= 31;
}

When it happens

Trigger: A user passes a date in the wrong format: `/fjdaily/2026-03-16` (dashes), `/fjdaily/2026/03/16` (slashes), `/fjdaily/260316` (6 digits), `/fjdaily/202603160` (9 digits), or any non-numeric string. The regex test fails immediately.

Common situations: User passes a date with separators (dashes, slashes, dots). User passes a 6-digit or 10-digit date. User passes a locale-formatted date string. User passes a date that is valid as a date but wrong as a format (e.g., `March 16, 2026`).
