Hi Roee,
It looks the error is due to blank feature param value in the json.
"name" : "my",
"features":[],
"params" : {
I have observed that many a times solr ltr returns generic error that 'Model
type does not
exist', but later actually found to be an issue with json. Just wanted to
share my experience.
Regards
Kamal
