How to resolve a validation error when updating a string list?
Problem:
A validation error appears during the string list updating.

Root cause:
This error occurs when two files in the workspace have the same file ID, and the same key occurs in both files.

Solution:
Ensure that the files in the workspace have unique file IDs. For details, see the File ID section.

You can use the Mass rename file IDs functionality (for details, see the Mass rename file IDs guide).
