Hey,
It seems that you have an invalid learning JSON.
When first using the Keyword Based Classifier, you should start with an empty JSON file, something like [] (basically, just create a text file with just [] in it and make sure the file extension is .json).
Then, you can use the Keyword Based Classifier inside a Train Classifiers Scope to add to the empty JSON relevant information based on the output of the Validation Station.
