TypeError After UnsetRule

[papaspiridis]

Hello, I want to ignore a holiday by using unsetRule. The holiday does not appear in the list returned by getHolidays however when checking for that date using isHoliday I get the following Typerror

const hd = new Holidays();
hd.init('GR', { types: ['public'] });
hd.isHoliday('2023-04-14'); //returns true
hd.unsetRule('orthodox -2'); //returns true
hd.isHoliday('2023-04-14'); // => throws error
Uncaught TypeError: Cannot read property 'inYear' of undefined
