Interface/Form

hello all,

Currently working on testing the interface. I see the following message "An Error has Occurred -Invalid Character "and the message action completed successfully. To identify the root cause deleted all the components in the UI and tried to test.I am getting the same message but in all scenarios action completed successfully and this particular interface as configured as process start form and same is used in the sites.. please let me know if any one faced the similar issue.  please refer the attachment for the message . Thanks

below is the SAIL code (for debugging deleted all the components except the button)

load(
 
  a!formLayout(
  
 
  buttons: a!buttonLayout(
    
 primaryButtons: {
       
a!buttonWidgetSubmit(
        
 label: "Create Incident",
      
   style: "PRIMARY"
        
        )
      }
     
    )
 
  )
