Solution Training Failed. Ask Support to use log key xxxxx to investigate trainer logs furtherIssue After upgrading to Orlando, the ML trainings were getting with the error "Solution Training Failed. Ask Support to use log key xxxxx to investigate trainer logs further" . The same definitions were working fine before Orlando. ReleaseOrlando and AboveCauseBefore Orlando everything was in a single table ml_solution_definition. From Orlando, we have introduced separate tables classification, similarity and clustering. The newly introduced tables are ml_capability_definition_classification, ml_capability_definition_similarity and ml_capability_definition_clustering. There is no action required from customers on the new tables. Service Now will move all the related data from ml_solution_definition to its respective tables. The old table still exists on the instance and the customer might be trying to train on the old table ml_solution_definition.ResolutionTrain the definitions on the new tables instead of the old table.Related Links[Classification] Solution Traininig Failed with "The header contains a duplicate name" caused by the same field set as one of the Input fields, as well as the Output field in the solution definition
