Predictive Intelligence - Similarity Solution Error in training

[anishkuti]

I have created a ML solution  in PI ->Similarity Solution Where I want to match incident to knowledge articles. I used the below solution definition 

Table

Knowledge [kb_knowledge]

Similarity Fields

short_description

Table to compare

Incident [incident]

Fields to compare

short_description

Filter

active=true^short_descriptionISNOTEMPTY^EQ

 

But when I am training this solution I am getting the bellow error . Can any help to find the reason ?

NSE0016:Failed to execute component similarityValidator : NCE0091:Invalid text column count, lookup set has no text column, but test set has text column.
