I additionally ArrayOutOfBoundsException which occurs while loading python

cannot parse complex functions. However, during unit testing, our python codes

ArrayOutOfBoundsException. So I changed the directory name for python functions.
> NullPointerException occurs when a simple query contains a python udf
