Error description

  • When executing a decision service that has multiple predictive
    models using the same Machine learning provider the execution
    fails. The issue is that the Machine learning provider paylaod
    cannot be deserialized since the same Machine learning provider
    is added several time. The following message can be found in the
    logs:   "localizedMessage": "Cannot deserialize instance of `co
    m.ibm.decision.ml.integration.client.MachineLearningProvider$Ma
    chineLearningProviderBuilder`out of START_ARRAY token\n
