Default business hour not found

Error message

Default business hour not found

What it means

During onDepartmentDisabled, after unlinking a department from its business hour, the code fetches the workspace's default business hour to close agents' caches for both hours. If findOneDefaultBusinessHour() returns null (no default business-hour record), it throws 'Default business hour not found'.

Solutions

1. Re-create/restore the default business hour record (re-enable business hours in settings so defaults are seeded)
2. Check the LivechatBusinessHours collection for the document with defaultValue/activeDefault flags
3. If disabling business hours entirely is intended, disable the feature before removing department links

const defaultBH = await BusinessHourRepository.findOneDefaultBusinessHour();
if (!defaultBH) {
	// re-seed the default business hour before disabling departments
}
await onDepartmentDisabled(department);

try {
	await onDepartmentDisabled(department);
} catch (err) {
	if (err instanceof Error && err.message === 'Default business hour not found') {
		// data integrity issue: create/restore the default BH record, then retry
	} else {
		throw err;
	}
}

When it happens

Trigger: Disabling a department that references a business hour while the instance has no default business-hour document in the database.

Common situations: Fresh or migrated installation where the default BH record was never created; default business hour removed manually from the DB; legacy data missing the default record.
