Error in Scoring

I got the " java.lang.NumberFormatException" error when running Score recipe on my LightGBM model.

In addition, I have confirmed that the input data features do not contain values that cause overflow.

Do you have any clues?

    Just to follow up on the community post as well as I know we have resolved this over a support. In case anyone else runs into a similar error the easy solution was to "Force original backend" in the scoring recipe.

    In this particular case, the Java Scoring engine would not work because of the specific model details.
