The error message basically means that the result of your XML query
contains not exactly one node. So either you have 0 matching node, or
multiple matching nodes (try ${yourQuery?size} to find out which). In
those cases a the resulting node list can't be automatically treated
as a scalar, hence the cryptic error message.
