Try the following

var caseType = execution.getVariable("caseType");
var payload = {“name” : “Mark as completed :” + caseType };
payload;

Okay

I see that you are using the http connector. I personally prefer to use external task.

As per the example in below URL, try setting Variable Assignment Type to String or Expression and put below

{“name” : “Mark as completed : ${caseType}"}
