Keyword based classifier trainer messes up keyword.json file

[jack.chan]

Im using keyword based classifier trainer to train a classifier.
But i notice it occasionally messes up the json structure in the learning path, which leads to exception the next time it runs the activity.

This is what happened to the json structure

Note that i didnt start with an empty learning json file. My learning file is prefilled with some keywords.

Other info:

1. my keyword based classifier trainer activity is in a parallel for each activity. Because i have to wait for all the documents to be classified (via action center) before i can continue
2. IntelligentOCRActivities package is the latest version

Once try Intelligent Keyword Classifier Trainer…

i moved the classifier trainer logic outside of the parallel for each loop and the problem is gone.
