Exception Error not showing up in diagnostics console

[Garrett_Weber]

I am trying to compose a test document to see if my placeholder will display the fragment correctly but when I attempt to compose I am repeatedly getting an exception error. I turned on diagnostics console but its not showing anything when this error occurs. What is my best course of action to try to troubleshoot/diagnose the problem on my template? Note this template works fine without this placeholder it also works fine when the field I'm evaluation is set to Yes but when the Default condition is met it gives this error.

Here is the exception information:

System.NullReferenceException: Object reference not set to an instance of an object.

I confirmed it was the right when I got the line in the diagnostics console its the correct existing fragment.

I recommend contacting your first line of support for more assistance.

Dear Garrett,
This could be a result of composing the test from an old form.As such the new placeholder that you have created in the template do not recognize the fields in the form. Submit a new form and choose that form as your test document and test the composition on it.
