After upgrading to 23.0.0, when we call .getBindings("python").getMemberKeys()) returns NPE

org.graalvm.polyglot.PolyglotException: java.lang.NullPointerException: Invalid parameter type passed to updater. Instance of type 'PythonMapScopeGen.InteropLibraryExports.Cached' expected but was 'null'. Did you pass the wrong node to an execute method of an inlined cached node?
