Predictive Modelling Use Case Problem
Hello everyone. I'm having problems working through the Predictive Modelling case study. All is going fine until I get to
Step 2. Training The Model, Part 4. Subsection 5: "Save and run the model before moving onto the next and final step."
I get the following error thrown at me even though the training model would appear to be running fine, corresponding to the notes and video.
Failed due to error: 'java.lang.NullPointerException: Cannot invoke "java.util.UUID.toString()" because the return value of "api.models.dataModeling.model.ModelingModel.getModelId()" is null'
Anybody seen similar or recognise such an issue?
Hi Dave, I will take a look at this error with Eduart who wrote the Use Case and get back to you, could you also send over a screenshot just for reference, thanks
what I think helped me with this error message was to delete the in-memory Database (at the end), connect it again and then let it run. Just repeating the last step often helped.
Hope that you can figure it out!
