JSON Enabled function returns Error when Empty value is passed #148
Description
Activity
The error is pretty clear that an attempt to convert null to an an object failed. Null input should result in a null object passed to the function handler.
{ "message":"Unhandled internal error in FDK", "detail":"An exception was thrown during Input Coercion: Failed to coerce event to user function parameter type class com.example.fn.HelloFunction$Input"}@rikgibson can you take a look at this? I'd rather we fixed this bug than have to add warning text to the Java tutorial (fnproject/tutorials#149).
What is the status on this issue?

After the adding JSON support for Java Fn function, if the function is passed an empty value, Fn returns:
{"message":"container exit code 2"} Fn: Error calling function: status 502The function does work with JSON data. If you pass:
or even
the function works fine. Tried modifying the function to test for null and isEmpty. Nothing like that worked. I'm guessing the function is throwing an uncaught exception.
