Athol cancels checks - error 16 "Invalid price (amount)". Where is the mistake?

Question

1C

The HTTP service in 1C receives a request with incoming parameters, looks for a sales document and makes a non-cash payment on it at the ATOL checkout. The amount sent to the service is arbitrary - it should be in the check. The problem is that when the declared amount is less than the amount in the sales document, it is not recalculated in any way when printing a check. Should I. I tried to recalculate algorithmically on the 1C side, but Atol cancels the check. The error description reads: {"error":{"code":16,"description":"Invalid price (amount)"}. In the table, all values ​​are recalculated, the payment values ​​are the same.

What could be the problem and how can it be solved?
