Provide reason why the field is invalid

[ruslantimofeev]

General information

• SDK version: 3.95.0-connect-alpha.5
• Environment: Both
• Browser and OS Any

Issue description

We would like to have the reason why the expiration date is not valid in the hostedFieldsInstance.on('validityChange') callback to display an appropriate error message for the user.

So far, the SDK only indicates if the field is valid or not, but for the expiration date it's invalid if

• it's expired
• too far in the future

Therefore we would like to display something like

• "Your card is expired"
• "The date too far in the future"

👋 Thanks for reaching out, this sounds like a solid feature request that we should vet. I'm going to forward this on to the appropriate folks to evaluate.
