I’m having intermittent issues with the .tokenize() method when using the webpayments SDK. The error it’s returning is: {“message”:“the tokenization request is already in process”,“type”:“TOKENIZATION_IN_PROCESS”} but I can’t find any documentation on what would be causing this. It only happens intermittently and is not always reproducible in either the sandbox or production environments

The error message “TOKENIZATION_IN_PROCESS” indicates that a tokenization request is already in progress. This error can occur if the .tokenize() method is called multiple times concurrently. The Web Payments SDK is designed to handle one tokenization request at a time. If you’re seeing this error intermittently, it might be due to a race condition in your code where .tokenize() is being called more than once before the first call has completed. To resolve this issue, ensure that .tokenize() is not called again until the first tokenization request has completed.

Is it possible that something triggered tokenization inadvertently?
