How are you starting the process in the case that is generating an error? Are you running it via debugging, or calling the API? In this case you will need to make sure data is passed into the process when it starts, since the process nodes are expecting some data.

If you're using this in the tutorial, you should make sure you're passing in the studentId as a parameter, since that's what is being used to query and update data.

I think more screenshots / description of how your process is configured and started could help us provide a good suggestion for what to look at.

Hey Stefan, thanks for the reply.

I followed the Process Model API tutorial: Pass a Web API Document Upload into a Process Model - Appian 21.3

Here's the error I'm receiving:

I'm thinking I need to create an expression rule that'll assign values to the CDT?

Can you share a few more details? Do you follow any tutorial? Code snippets? Screenshots?
