Orders are not uploaded from Bitrix to 1C on the Aspro theme. How to fix?

Question

1C-Bitrix

Hello.
Orders are not uploaded from Bitrix to 1C on the Aspro theme.
Error in 1C:
{CommonModule.B_SiteExchangeServer.Module(1456)}: Error calling context method (SendForProcessing): Internet error: Transferred a partial file
Failed to get data from server. Check that the server address, port, username and password, and Internet connection settings are correct.
Failed to read the data downloaded from the server.
Login and password are correct.
If you rename the /bitrix/modules/aspro.max folder, then the orders are uploaded to 1C without errors.
As I understand it, the problem is in the formation of xml using the theme, but it is not clear where this happens. Where is the theme that adds or cuts?
