Yes, decoding is performed on the received message.  Also, the element
named *Response.

I expect that the response contains an empty <payment_information/>   But
it may also be not empty with an unexpected or out-of-order field.

See $trace->printResponse(pretty_print => 1);

Fix the schema or server ;-)

The first error is only the last (fatal) issue.  After that, it lists
all issues, sometimes with more information.
