What does it mean to receive an "undefined error" when running a Python script and executing the get output schema function?

edit

An "undefined error" when running a Python script and executing the get output schema function means that there is an issue within the script that is causing the output schema to not be defined or returned properly. This could be due to a syntax error, an incorrect use of functions or variables, or other programming errors. It is important to debug the code and identify and fix the issue to ensure that the output schema is defined correctly and the script can run as intended.
