  Cause
  This error typically occurs when:
  
  A chip is expected to receive a parameter through a defined port, but the parameter is not defined in the chip's configuration.
  The parameter might be incorrectly named or not included in the chip's interface.

  Check Chip Configuration:
  
  Open the configuration of the chip that is causing the error.
  Verify that the required parameter (&3) is defined in the chip's interface.
  
  
  
  Verify Port Mapping:
  
  Ensure that the port (&1) is correctly mapped to the chip (&2) in the consuming application.
  Check if the parameter is being passed correctly from the calling application to the chip.
  
  
  
  Update Parameter Names:
  
  If the parameter name is incorrect, update it in the calling application to match the expected name in the chip.
  
  
  
  Test the Chip:
  
  After making the necessary changes, test the chip in the context of the application to ensure that it is receiving the required parameters correctly.
  
  
  
  Check Documentation:
