Service Connect PO approval process error

We created a workflow through Service Connect for PO approvals. Got this error message a few times though and I can’t figure out what the problem is:

<?xml version="1.0" encoding="utf-16" standalone="yes"?>

<msg:req tag=“POApvMsg.Erp.Proxy.BO.POApvMsgImpl.GetByID”>

(There’s more, but it contains the employees name, email, etc.)

Any ideas on what it means?

Actually, there’s two errors. Here’s the second one:
