I started the process with an interface (Create Exam) and then I want to store it in the database, but I guess there is some problem with the database or Record type, Can anyone please help me understand what I am doing wrong?

In that CDT, I am missing a auto-incremented primary key field.
That error message tells you that the data you pass is empty. In that failed process instance, check the process variable. If that contains the data from your interface, then check the configuration of your database node.
Hello, I tried your solution and Gave ExamID as Primary key and auto increment even after that when I am clicking the submit button an error is shown that it is passing the (Marks Per Question) parameter as null.
I checked the type of the parameter it is integer then I checked the interface for (Display value /Save input to) those are also configured to the CDT.
Could you suggest what could be the problem?
Did you check the second part of my answer?
create one id field in cdt type int , and then make primary key,
check rule inputs and data store entity
Check process variable is it map with CDT and parameter should be check
Is your process variable Parameterized? In a start form the variables you pass should always be parameterized. Also you should always have a integer primery key for determining a unique row.
Hi everyone, thank you so much for helping me.
I was able to make it work
