I have been following this guide - How to use MongoDB Client-Side Field Level Encryption (CSFLE) with Node.js/ by Joe Karlsson to test out the MongoDB CSFLE.
In doing so, in the step of creating the data key in local key vault store [https://developer.mongodb.com/how-to/client-side-field-level-encryption-csfle-mongodb-node/#create-a-data-key-in-mongodb-for-encrypting-and-decrypting-document-fields] the data key successfully is created but the keyAltName is not attached to the data key’s document.
I tested this multiple times and there is nothing wrong in my code and I’m following the guide as it is. I can’t understand what is causing this issue. The data key creation is successful but without the keyAltNames field. A help here would be really appreciated.
