Invalid run ID: ${id2}

Error message

Invalid run ID: ${id2}

What it means

compareRunIds() validates both arguments; this throw fires when the SECOND run ID (id2) fails isValidRunId() — i.e. it is not a valid ISO 8601 UTC timestamp string. id1 was already validated successfully at this point.

 * Can be used as a comparator function for Array.sort().
 *
 * @param {string} id1 - First run ID to compare
 * @param {string} id2 - Second run ID to compare
 * @returns {number} Negative if id1 < id2, positive if id1 > id2, zero if equal
 * @throws {Error} If either run ID is invalid
 *
 * @example
 * compareRunIds('2024-01-15T10:00:00.000Z', '2024-01-15T11:00:00.000Z') // returns negative number
 * ['2024-01-15T14:00:00.000Z', '2024-01-15T10:00:00.000Z'].sort(compareRunIds)
 * // returns ['2024-01-15T10:00:00.000Z', '2024-01-15T14:00:00.000Z']

Solutions

1. Validate id2 with isValidRunId(id2) before calling and regenerate or discard it
2. Convert Date objects to ISO strings: id2.toISOString()
3. Filter collections with ids.filter(isValidRunId) before sorting

Example fix

// before
compareRunIds(id1, new Date()); // Date is not a string
// after
compareRunIds(id1, new Date().toISOString());

if (!isValidRunId(id2)) throw new Error(`Cannot compare invalid second run ID: ${id2}`);
if (id2 instanceof Date) id2 = id2.toISOString();

function isStringRunId(v: unknown): v is string {
  return typeof v === 'string' && isValidRunId(v);
}

try {
  return compareRunIds(id1, id2);
} catch (err) {
  if (err.message.includes(id2)) {
    id2 = new Date().toISOString();
    return compareRunIds(id1, id2);
  }
  throw err;
}

When it happens

Trigger: compareRunIds(goodId, 'invalid'); sorting arrays where the second element or later entries are corrupt; passing a Date object or number timestamp instead of a string as id2.

Common situations: Datasets with one malformed record; passing new Date() (a Date, not a string) as id2; IDs truncated by a fixed-width column or log parsing.
