Merchant initiated transactions fail using stored payment method in cybersource

Question

I am using CyberSource and here is what I am trying to do:

1. make payment with PAN (customer initialed transaction)
2. store payment for future use
3. use stored payment method for merchant initiated transactions

Documentation I used: https://developer.cybersource.com/docs/cybs/en-us/payments/developer/ctv/rest/payments/credentials-processsing-intro/credentials-mit-recur-intro.html. Particularly looking at following sections of the documentation:

1. Initial CIT Recurring Payment with a PAN
2. Subsequent MIT Recurring Payments

I believe, I follow documentation closely, however, the result that I get is not ideal. First transaction is successful, and it looks like payment method is stored on file. However, following merchant initiated transactions fail with following error: The credit card number is either missing or invalid

Below is my implementation, I am using C# and CyberSource's SDK. I would appreciate any help, thanks you in advance!
