Here, you are iterating over a /Page dictionary (doc.Pages[1]), which
is a real dictionary.
No issues when iterating over real dictionaries with pdfe.dictionarytotable().

But the /Contents entry of this dictionary refers to a stream. And the
first part of
a stream object is a dictionary. But you cannot use pdfe.dictionarytotable() in
this case.
