What do expect to encrypt the Pin under, I don't see any key in your request?

You need to build and set the right fields or fields to match your field definitions.
If you don't set a field to a value, it won't contain anything - as appears to be the case here.
Is your code setting a field value that is not making it out into the Message sent to the HSM?
If you share all the details in a smart question (Google 'how to ask a smart question to form one), I am sure your problem will be obvious to you.

It's a group forum and others can assist where possible.

- gather the details needed to help you help yourself
- focus your question on the issue and detail needed so we can try and help
If you had tried to do as I asked, we might have moved forward, since you have not we won't for now.
Have fun.
