Exception when calling Function Import for JPA Model

Hi,

Your support is highly appreciated on below Function Import issue.

I have followed the tutorial to add function import for JPA Model in the following Olingo documentation link.

https://olingo.apache.org/doc/odata2/tutorials/jpafunctionimport.html

When I call the function import I am receiving the following exception:

"OData - JPA Runtime: Internal error [null]"class java.lang.reflect.InvocationTargetException : null

When I remove the function import parameter from the url. The service will through the following message: Missing parameter.

FYI, other than the function import every thing is working fine like calling the service metadata, calling JPA Models, calling JPA Models with their keys, and calling JPA Models with filters.
