The number of distinct words in a sentence. What is a stack trace, and how can I use it to debug my application errors? Is there something I can do at this point to grab the stacktrace? Your trouble is that although you can suppress the stacktrace of the exception your own code threw, there is nothing you can do about the exception it will be wrapped into by the framework. Note that the top-most function in the stack trace is the one that was executed last, hence, that is the function where the exception occurred.
