412 - Precondition Failed

The request can not be performed because a precondition check failed. Usually, this means that the client sent a PUT or PATCH request with an out-of-date _revision property, probably because some other client has modified the entity since it was retrieved. The client should re-fetch the entry, apply any desired changes, and re-submit the operation.
