I set the following time slots:
10am - 11am
11am - 12 pm
12pm - 1pm
If today timeslots are disabled (such as 10 am-11 am, 11 am-12 pm are disabled), tomorrow you can't select these time slots too, but other slots still can be selected. It says "the Timeslot field is a required field."
There is a bug in our Order Delivery Date module. The module JS misses checking isToday, so when any timeslot is disabled, it will automatically assign the null value => error, we need to add the condition to check isToday
To temporarily resolve the issue, please edit the file: app/code/Bss/OrderDeliveryDate/view/frontend/web/js/view/delivery-date.js as below:
Or download the file attached below to override the current file on your site.
