"The request does not match the hsm format", what does it mean?

Question

API

Good afternoon, I'm trying to implement the API of the nalog.ru service.
I do everything according to the example here:
https://gist.github.com/reinhurd/bf16877c49140c913...
At the last request, when I pass I get the result: Error code: 452 What does this mean, and most importantly, how to fix it?
<ns:MessageId>".$messageId."</ns:MessageId>
Запрос не соответствует формату hsm
