That will work if the binding is being created on an endpoint which is
not a "direct" connection. Otherwise, you need to ensure the keys and
values are binaries. There is a bug open for this - it's a mistake in
the erlang client which the shovel uses, but alas it's not been fixed
yet. So if in doubt, use something like:

{'queue.bind',
       [{exchange, <<"my_exchange">>},
        {queue,    <<"my_queue">>},
        {arguments, [{<<"x-match">>,         longstr, <<"any">>},
                     {<<"headerName">>,      longstr, <<"headerValue">>},
                     {<<"otherHeaderName">>, longstr, <<"otherHeaderValue">>}]}]}
