class_docstr: Base Ax exception.
  
  All exceptions derived from AxError need to define a custom error message.
  Additionally, exceptions can define a hint property that provides additional
  guidance as to how to remedy the error.
code: def __init__(self, message: str, hint: str = "") -> None:
      self.message: str = message
      self.hint: str = hint
  
label_desc: Use image node_id 1 to create a new AxError object from inherited base classes: Exception with example: obj = AxError(message, hint)
