When using the replacePrefix function from dexie to modify tree structure paths, the transformation works correctly in offline mode but fails after syncing with the server. Instead of executing the string replacement, the server returns a serialized version of the operation, breaking the application's tree structure.

db.treeNodes
  .where('parentPath')
  .startsWith(`${node.parentPath}${node.id}/`)
  .modify({
    parentPath: replacePrefix(node.parentPath, newParentPath)
  });

• When offline: This operation works as expected, properly modifying the parentPath strings
• After sync: The server returns an object instead of the transformed string:

{
  "parentPath": {
    "replacePrefix": ["old_prefix", "new_prefix"]
  }
}

This breaks the application as it expects parentPath to be a string, not an object.
