Error while training solution: NSE0016 / NCE0019:Failed to train text vectors of method TFIDF

[oliveira_jhg]

Hi guys, I am trying to generate a similarity solution but I am getting the following error:

NSE0016:Failed to execute component lookupVectorizer : NCE0019:Failed to train text vectors of method TFIDF

I only found the reference to include the parameter TFIDF in the solution definition, but still not working.
