# 54151: List Item not found

Log Level: ERROR

## Description

This error occurs when your request targets a Sync List item at an `Index` that does not exist in the specified list. Sync List items are addressed by index, and an item can stop existing if it was deleted or if its `itemTtl` expired.

### Possible causes

* The `Index` value in your request does not match an existing item in the target Sync List.
* The List item was deleted after it was created.
* The List item expired because a `ttl` or `itemTtl` value was set on the item.

### Possible solutions

* Verify that you are using the correct Sync List SID or `unique_name` and the correct `Index` for the item you want to access. Sync List item requests use `Index` to identify the item.
* Read the List items before you fetch, update, or delete an item so you can confirm that the item still exists and use a current index value.
* If the item was deleted or expired, create a new List item or remove the stale reference from your application.
* Review any `ttl` or `itemTtl` values if your application expects the item to remain available longer.
