I think it would help if you could show the code that produces the error. The data alone (what you've shown) doesn't produce any error messages.

diagnostics says

$ echo "Not a HASH reference" | splain
Not a HASH reference (#1)
    (F) Perl was trying to evaluate a reference to a hash value, but f
+ound a
    reference to something else instead.  You can use the ref() functi
+on to
    find out what kind of ref it really was.  See perlref.
