Summary0010081: calculation from spa and libeufin server doesn't match
DescriptionI found out this when testing another issue.

The first query passes, the second request contains the value that the SPA calculate based on the configuration and get the error "Wrong currency conversion" but it may be related to the credit/debit amount.
