This error indicates that a specific method in the code is being called multiple times for the same instance, which is not allowed.
  Cause:
  
  
  Method Invocation: The error usually arises when a method that is designed to be called only once per instance is invoked multiple times. This could be due to:
  
  Incorrect logic in the program or function module.
  A loop or repeated call that inadvertently tries to execute the method multiple times.
  Mismanagement of object instances, where the same instance is being reused incorrectly.
  
  
  
  State Management: The method may rely on certain state information that is altered after the first call, leading to the error when it is called again.
  
  
  Solution:
  
  
  Review Code Logic: Check the code where the method is being called. Ensure that the method is only invoked once per instance. You may need to refactor the code to prevent multiple calls.
  
  
  Instance Management: If the method is part of an object-oriented design, ensure that you are creating new instances of the object when needed, rather than reusing the same instance.
  
  
  Debugging: Use debugging tools to trace the execution flow and identify where the method is being called multiple times. This can help pinpoint the exact location in the code that needs to be corrected.
  
  
  Error Handling: Implement error handling to manage situations where the method might be called incorrectly, providing informative messages or alternative flows.
