HI Ravi,

The error message "Account-LE - Account Layout - End User duplicate value found: PlatformActionListId duplicates value on record with id: 0Jo78000000wFILCA2" indicates that there is a duplicate value in the PlatformActionListId field on the Account Layout - End User record with the specified ID. This error can occur when there are multiple records with the same value in a field that is marked as unique, or when there is a problem with the data deployment process

To resolve this error, you can try the following steps:
- Review the records in the affected object and look for any duplicates in the PlatformActionListId field. If duplicates are found, delete or merge the duplicate records.

-If the error occurred during a data deployment process, review the deployment logs and check for any errors related to the PlatformActionListId field. If necessary, adjust the deployment settings or data to resolve the error.
