Thank you for your question! 

I’d like to recommend to bring more details and context to your initial inquiry. For example:

• Are there any permission or path issues preventing the .ser file from being generated?
• Is the workflow editor unable to locate the class due to missing entries in the resource bundle or incorrect classpath?

Please add screenshot(s) to better understand what you are trying to do in your process.
