Custom Event User objectId Error

Am debugging a custom event logic using CodeRunner and getting the error

In the Custom event, am first trying to get the objectId of the logged in user like so

@Override
 public Map handleEvent( RunnerContext context, Map eventArgs )
 {
 // add your code here
 String parentObjectId = com.backendless.servercode.InvocationContext.getUserId();
......}

What could i be missing?

Hello,

Instead of “com.backendless.servercoce.InvocationContext”, use the “context” object passed into the handleEvent method.

Like so

@Override
public Map handleEvent( RunnerContext context, Map eventArgs )
{
// add your code here
String parentObjectId = context.getUserId();
......}

Further to this, how do i get the

Yes, like that.

You could attach a debugger to the process and inspect the exception in the debugger. See the docs for more info:

Hello Mark,

Using the “context” object passed into the handleEvent is working, at least eliminates the original problem, thanks.

But I am now getting the error “Custom business logic execution has been terminated because it did not complete in permitted time - 7200 seconds” with my server side custom event.
7200 seconds is equivalent to 2 hrs yet the error is being returned after just a few seconds.
It executed once though and has now permanently reverted to this.
I have gone as far as simplifying the logic being executed in the custom event to return just a few table counts and am still getting the same errror.
CodeRunner does not move beyond “Waiting for events…”

Hi George,

I see you opened another topic for the other problem. Please use that thread for discussing it.

I will mark this one as “Solved”.
