Is this be caused by the code in org.python.antlr.adapter.ExprAdapter?
The call chain is:
org.python.antlr.ast.Expr.setValue
org.python.antlr.adapter.AstAdapters.py2expr
org.python.antlr.adapter.ExprAdapter.iter2ast
org.python.antlr.adapter.ExprAdapter.py2ast


The py2ast method only includes type checks for PyInteger, PyLong,
PyFloat, PyComplex, PyString, and PyUnicode.  All other elements (like
an 'Assign' class) would default to null, if they were set via 'setValue'.
