<a name="agreement-error-codes-resource-not-found"></a>

The `ResourceNotFoundException` includes `resourceType` and `resourceId` fields that identify the resource that could not be found. The following table describes the scenarios that can cause this exception for each resource type.

**Note**  
For security reasons, the same error is returned whether a resource does not exist or the caller does not have access to it. This prevents enumeration of valid resource identifiers.
