[jira] [Created] (ASTERIXDB-2884) Nested UDF calls with constant argument NPEs

Ian Maxon created ASTERIXDB-2884:
------------------------------------

             Summary: Nested UDF calls with constant argument NPEs
                 Key: ASTERIXDB-2884
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-2884
             Project: Apache AsterixDB
          Issue Type: Bug
          Components: FUN - Functions
    Affects Versions: 0.9.7
            Reporter: Luke Ren
            Assignee: Ian Maxon
             Fix For: 0.9.7


If you have a Python UDF with a body like:
{code:python}
def echo(a):
    return a
{code}

And then define and subsequently call it as a SQL++ UDF nested within itself with a constant argument like so:


{code:sql}
SELECT echo(echo(5))
{code}

A NPE is thrown.
