# 54201: Map Item not found

Log Level: ERROR

## Description

This error occurs when your request references a Sync Map item by `key`, but that item does not exist in the specified Sync Map.

### Possible causes

* The `key` in your request does not match an existing item in the target Sync Map.
* The item was deleted from the Sync Map.
* The item expired and was removed after its TTL elapsed.

### Possible solutions

* Verify that you are sending the correct `ServiceSid`, `MapSid` or `unique_name`, and item `key` for the Sync Map item you want to access.
* Read the items in the target Sync Map to confirm that the item still exists before you fetch, update, or delete it.
* Re-create the item if it was deleted or expired.
* If you use `ttl` or `itemTtl`, update the item with a new value before it expires when the item needs to remain available longer.
