ValidateCustomerPaymentProfile Request Returns E00027 Error

[pvaldivia951]

Hello, I need help understanding an error message I receive when making a request to the following endpoint https://developer.authorize.net/api/reference/index.html#customer-profiles-validate-customer-payment...

Here are the request and response. I removed personal credentials and private information where key values in the JSON are empty strings. I want to understand the meaning of the response message "There is one or more missing or invalid fields." in the response body.

What fields could I possibly be missing in the request or what fields could possibly be invalid? I would appreciate any feedback on this matter. Thank you in advance and let me know if more info is needed.
