ML Solution Definition is throwing error during training

[astha_chaubey]

Hi All,i

I activated the Agent intelligence plugin and trying to run Machine Learning on a custom table by creating ML Solution Definition records, however when click on "Update and Train" UI action it is always throwing an error saying- 

Training terminated due to Exception. Executing dedup task failed. text columns can not be null or empty

Please see screenshot

My custom table contains 40000+ records and none of the fields in any record are empty. 

I tried to create a new ML Trainer Definition record and tried to add that in my ML Solution Definition record, and clicked on "Update and Train", but now ML Solution record is in state "Waiting for training" endlessly and training is never getting started, not sure what the issue is.

Please help me resolve these issues.

Is this sorted out now after 2 years, I still find ourselves in the same issue. HR case categorization solution never trains but gets cancelled as soon as we update and train. Is this also because its a custom category that we are using?
