The following error appears when editing an existing Service Instance from K2 Management:

SmartObject Server Exception: Type: System.IO.FileNotFoundException is not allowed for deserialization.


Instructions 

  • This may be due to custom service brokers that are missing. Please review the host server log to identify them. You should see an error message in this format:
    "Error","SmartObjects","10045","ExecuteSmartObjects","SourceCode.SmartObjects.Runtime [ExecuteInstance(byte[] brokerPackageAx, byte[] insertTable)]","10045 Broker Execution Exception [General Exception:] : System.IO.FileNotFoundException - Could not load file or assembly 'file:///{Path to custom service broker dll file}' or one of its dependencies. The system cannot find the file specified."
  • Ensure that the file exists in the path specified in the error message then restart the K2 Server service.
