Kamuela Lau commented on SOLR-12367: ------------------------------------ A similar ClassCastException may show up for other LTRScoringModels (such as entering an int/long in matrix, ), such as NeuralNetworkModel (in particular, thinking of matrix/bias values for layers). Current patch will not change the ambiguous message for NeuralNetworkModel... > When adding a model referencing a non-existent feature the error message is > very ambiguous > ------------------------------------------------------------------------------------------ > > Key: SOLR-12367 > URL: https://issues.apache.org/jira/browse/SOLR-12367 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level.
