Error in V2 analytics verification

I’ve been converting to the new web api payments. When I submit the card to get a token, I’m getting a failure that did NOT happen during all my sandbox testing.

I am getting a valid token response of:
tokenize(paymentMethod) tokenResult:{
“details”: {
“card”: {
“brand”: “VISA”,
“expMonth”: 8,
“expYear”: 2024,
“last4”: “88XX”
“method”: “Card”,
“billing”: {
“postalCode”: “98XXX”
“status”: “OK”,
“token”: “cnon:CBASEB5ZR47AStZezNtxJzGgWbo”

The error is: frame.html:1 POST 400

The promise then fails with:
index.php?dispatch=checkout.checkout:1696 Uncaught (in promise) TypeError: Cannot read properties of null (reading ‘classList’)

I am not calling this directly, so I’m assuming it is coming from code within the API. How do I get beyond this?

So the payment doesn’t complete cause of this error? In the above you do have the source_id. :slightly_smiling_face:

Correct, it errors out and the remaining JS does not execute.

Is this with our Quickstart? :slightly_smiling_face:
