Date must be YYYY-MM-DD: ${date}

Error message

Date must be YYYY-MM-DD: ${date}

What it means

parseDate requires the date in strict YYYY-MM-DD form via regex ^\d{4}-\d{2}-\d{2}$. Any other format — slashes, missing zero-padding, extra whitespace, timestamps — throws this ArgumentError before the real-calendar check runs.

Solutions

1. Format the date as YYYY-MM-DD with zero-padded month and day: 2026-08-01.
2. If you have a Date object, use date.toISOString().slice(0, 10).
3. Trim the value and strip any time component before passing.
4. Normalize MM/DD/YYYY or DD/MM/YYYY inputs by reordering parts before invoking.

Example fix

// before
--date "08/01/2026"
// after
--date "2026-08-01"

function isIsoDateShape(d) {
  return /^\d{4}-\d{2}-\d{2}$/.test(String(d).trim());
}
// from a Date object:
const iso = new Date().toISOString().slice(0, 10);

try {
  await reimburse({ date });
} catch (e) {
  if (e instanceof ArgumentError && e.message.includes('Date must be YYYY-MM-DD')) {
    console.error(`Got '${date}'. Use zero-padded YYYY-MM-DD, e.g. 2026-08-01`);
  } else throw e;
}

When it happens

Trigger: dates like '2026/08/01', '2026-8-1', '01-08-2026', '2026-08-01T00:00:00Z', '2026-8-01' or values with leading/trailing spaces.

Common situations: Locale-formatted dates pasted from spreadsheets (MM/DD/YYYY); programmatic callers passing ISO datetime strings; shell interpolation inserting whitespace; users from slash-date locales.
