onPreCheckoutQuery will not handle queries if OrderInfo contains non-nullable value only in one field

[Towich]

I have an issue with sendInvoice and onPreCheckoutQuery

If sendInvoice have only requireEmail = true but doesn't have all of this:

requireName = true,
requirePhoneNumber = true,
requireShippingAddress = true

then onPreCheckoutQuery will not handle preCheckoutQuery.

I think It's because class OrderInfo have only non-nullable fields, so I guess fields can be nullable

Hello and thank you for your issue and full description. I will publish 20.0.1 asap (I think, this night by UTC), could you please check it and close this issue if it will be resolved?

I checked in 20.0.1, but this solution wasn't fix it, onPreCheckoutQuery not handle this query

Bug steps:

1. Send invoice to user (sendInvoice() with requireEmail = true)

2. Click on "Pay" on message:

3. Click on "Pay" in invoice:

4. Enter a password:

5. After a few seconds this message appears

If I don't use requireEmail = true in sendInvoice() it's works successful
