This error indicates that the system expected a value of type "Time," but it received a different type instead.

  Review Rule Configuration: Go through the configuration of the rules and expressions in BRF+ to ensure that they are set up correctly and that the expected types match the actual types being used.
  Debugging: Use the debugging tools available in BRF+ to trace the execution and identify where the type conflict is occurring. This can help pinpoint the exact location and cause of the issue.
