This error typically arises when there are conflicting entries in the search configuration, particularly concerning templates, request identifiers, attribute groups, and language settings.
  Cause:
  
  Duplicate Entries: The error is primarily caused by having multiple entries in the search configuration that share the same key attributes (template, request, attribute group, and language).
