Error when calling showWaterfall

[sbsrouteur]

Hello,

I am relatively new to ML, and am trying to use xgboost explainer to understand the outcome of some linear models I am building.
Following the example at:
article on xgboostexplainer
I have adapted the sample code for my model.
I can build an explainer, and run explainPredictions without errors.

However when trying showWaterfall, I get the following error message.

`Extracting the breakdown of each prediction...
|================================================================================| 100%

DONE!
Error in slice.xgb.DMatrix(object, idxset) :
INTEGER() can only be applied to a 'integer', not a 'double'`

What does this mean I did wrong?
