Hope someone can help with this. I'm experimenting with the MeaningCloud extension but I keep getting the error:
  • Exception: com.rapidminer.operator.OperatorException
  • Message: API Engine error: Missing required parameter(s): txt, url, doc [200]
  • Stack trace:

    No suggestions here so I uninstalled the latest version of RM Studio and reinstalled an earlier one.  That fixed the problem.  Guess I'll have to wait until the vendor upgrades the operator before I can upgrade as well.
