AP Invoice Approval - New Participant using SQL and XPATH expressions

For FinApInvoiceApproval, trying to derive an approver by adding a new participant, and creating asignees based on names and expressions. The asignees type is User, and issuing a query using the following variable:(/task:task/task:payload/ns2:findInvoiceHeader1Response/ns2:result/ns1:Value/ns1:InvoiceId).

The type of the expression was updated from STATIC to XPATH in the task definition file from the SOA composite.

After submitting an invoice for approval, the approval errors out with the following message:'The XPath expression failed to execute; the reason was: oracle.xml.sql.OracleXMLSQLException: ORA-00936: missing expression.'

When following the same approach but hardcoding an invoice_id, as opposed to using the variable, the approval works as expected.

Why is the variable(/task:task/task:payload/ns2:findInvoiceHeader1Response/ns2:result/ns1:Value/ns1:InvoiceId) is not returning the invoice id?
