This error typically arises when there is an attempt to create or add a key (such as a token) that already exists in the system, leading to a conflict.
  Cause:
  
  
  Duplicate Key: The most common cause of this error is that the key you are trying to add already exists in the database. This could happen if:

  Delete Duplicate Tokens: If you find that the token already exists and is not needed, you can delete the duplicate entry. Ensure that you have the necessary authorizations to perform this action.
  
  
  Review Parallel Processes: If multiple users or processes are trying to add the same token simultaneously, coordinate with your team to avoid conflicts. Implementing a locking mechanism or a queuing system may help.
  
  
  Data Consistency Check: Run consistency checks on the relevant APO data to identify and resolve any inconsistencies that may be causing the error.
