Why is there no exchange of payment documents in 1s-Bitrix?

Question

1C-Bitrix

DD, when exchanging orders with the site, we get such a server response, the internal accounts on the site are all disabled, the exchange only works for uploading payment documents, if the PKO documents (cash payment) pass and we see it on the site, then the sales document (clearance) issues such an error perhaps someone faced similar and there are solutions?
