I think I found a bug in in the production version of square.js
Here’s how I produced it.
On my payment screen, I made javascript execute the card object (not google or apple pay).
Then I purposely entered an invalid credit card number as follows:
Card number: 4800 0000 0000 0004
Expiry: 11/33
CVC: 911
Zip code: 11111
When I clicked the pay button (button the fetches the token and attempts to complete payment), a normal failure result occurs (claiming the bank refused the transaction). But after clicking it about 6 times in a one minute period with the same info above, I get the following error in my javascript console (you’d see this in firefox developer tools):
error
TokenizationError: Tokenization has failed
An unknown error has occurred

square.js:3
I was hoping to receive some error code about excessive attempts, but this unknown error confuses me.
Is there something else I can do to rectify this?
I don’t want it where one crazy customer clicks the pay button 50 times a second and causes the system to NOT work for the next customer that sincerely wants to make a purchase.
