In our HEDGE project, we notice the following exception which seems to occur when a smart connector is stopped (via REST API) while a Post KI is active. Instead of these exceptions in the log (and possibly status 500 messages back to the KB) we should look for a better way to deal with them. I see two options:

  • Either we stall the stopping until the Post KI is done (not sure if that's even possible)
  • Or we interrupt the active Post KI (which seems to occur automatically due to the java.lang.IllegalStateException: The SmartConnector cannot be used anymore once it is stopped exception and create a nice error message to send back to the knowledge base with the appropriate message.

See part of the log below and more in the attached file.
