On Magento 2.3.0 i created simple product Then i added 1 customizable option with checkbox not required. After saving product when i click on Add to cart button without selecting checkbox (Because it is not required field) it shows me this error
The product's required option(s) weren't entered. Make sure the options are entered and try again.
I searched for this error and i found that someone raised this issue before on github
Definitely this is critical bug on magento 2.3.0 version and still not fixed by them. We updated our store from 2.2 to 2.3 on dev server for testing.After facing this error it seems like its not good solution to update to magento 2.3 version. Can anyone provide me quick fix of this error ?
