I'm using the frappe gantt chart package & setting the start date as "2022-04-18" but for some reason the bar is showing as one day before, is there a way for me to set an offset to correct this?

Setting Items:

return {
     start: '2022-04-18',
     end: '2022-05-20',
     name: project,
     id: "Task " + i,
     progress: 100,
};

Setting Chart:

var gantt2 = new Gantt("#gantt-1", tasks, {
    date_format: 'YYYY-MM-DD',
}
