54151: List Item not found

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.

• 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.

• 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.
