Try Catch Throw in ServiceNow

[rcruzsnow]

So I've setup a code in a try-catch statement where it throws the code if it passes the given if-statement:

if(requestEntry.cmdb_ci == null) throw "CI is missing";

Seems correct right? But when I've executed the test on the code, a certain error came out:

"Cannot convert CI is missing to com.glide.rest.service.custom.errors.ScriptableServiceError (sys_ws_operation.a001d9284fd5ba0022493faf0310c7da.operation_script; line 110)"

Seems that the given class is not allowing me to throw the error message that I've created. Do you have any suggestions on how to work around this?

Try requestEntry.cmdb_ci === null.

What I'm trying to look for is the function of the Throw statement in ServiceNow, not the operator. The suggestion you provided is simply an operator which is for a strict comparison.
