#### Causes

This error may be triggered when attempting to update the Card Registration object with an invalid value for the `RegistrationData` parameter.

The `RegistrationData` value can be incorrect if:

* Data sent to the tokenization server was inaccurate, therefore the returned data is invalid.
* The wrong `RegistrationData` is used (missing character, formatting, etc.)

#### What to do

In such cases:

* Check that the correct value was used for the `RegistrationData` parameter.
* Check that correct values were sent to the tokenization server (`AccessKey`, `PreregistrationData`, and card information).
