  Cause:
  The error occurs due to the following reasons:
  
  Duplicate Interface: The interface you are trying to create or integrate already exists in the target system or context.
  Configuration Issues: There may be misconfigurations in the integration settings or the data model that lead to the system attempting to create a duplicate entry.
  Data Migration: During data migration or system upgrades, existing interfaces may not have been properly accounted for, leading to conflicts.
  
  Solution:

  Modify or Delete Existing Interface:
  
  If the existing interface is not needed, consider deleting it or modifying it to fit your requirements.

  Review Integration Configuration:
  
  Check the configuration settings for the integration process to ensure that there are no misconfigurations leading to the attempt to create a duplicate interface.
  Ensure that the naming conventions and identifiers used are unique and do not conflict with existing entries.
