• After a specific invalid input, subsequent valid inputs will still keep outputting the same null error message

Steps to reproduce

• When asked for a valid number within the range [1 to 9], enter 0
• Command will exit with null error:

  •   An error occurred with the message: null
      Please check your command Syntax.
       If you need assistance use `help` command to know further about each command syntax.```
    

  • Null error message has an additional space before If you need assistance
• Entering a subsequent valid command will still contain the persistent error message.
