More info is needed to answer directly, but here are some questions that may suggest an answer:

How did you launch the Regression Learner app, for example, from the command line, or from the app gallery? Did this error occur immediately when you launched app, or later, while using the app? If you launched the Regression Learner from the commandline, did you provide any workspace variables as arguments? What is the type of those variables? Did you use any dot indexing for those variables? On which platform are you running?
