does opt.retryOnFail have a default value? same for the other cases below.

Suggested change

	if (opt.retryOnFail(lastError) || (opt.truthy && result) || (!opt.truthy && result !== undefined)) {
	if (opt.retryOnFail?.(lastError) || (opt.truthy && result) || (!opt.truthy && result !== undefined)) {

Yes, on line 265 retryOnFail: () => false, defaulted to false same as before
