org.apache.solr.ltr.model.MultipleAdditiveTreesModel

Trying to upload a simple MultipleAdditiveTreesModel, however I am getting
an error
"msg":"org.apache.solr.ltr.model.ModelException: Model type does not exist
org.apache.solr.ltr.model.MultipleAdditiveTreesModel"

Root cause seems to be a syntax error in the model file?
I did copy this from the example
https://lucene.apache.org/solr/guide/6_6/learning-to-rank.html#LearningToRan
k-Examples

Made sure all the values have surrounded by quotes

Made sure features specified in the model are in the features file

Did anyone else face this? what was the resolution?

Thanks,
Roopa
