HTTPoison doesn't accept this custom header

I have a curl request of the below that works but when I translate it into the below I get the following error what is wrong with this header - I feel I've done it every possible way. 

url = "https://content.dropboxapi.com/2/files/download"
header = [ {"Authorization", "Bearer #{token}"}, {"Dropbox-API-Arg", "{\"path\": \"/dropboxtest/image.jpg\"}"} ]
HTTPoison.post(url=url, header=header)

** (ArgumentError) argument error
    :erlang.iolist_to_binary([{"Authorization", "Bearer <removed>"}, {"Dropbox-API-Arg", "{\"path\": \"/dropboxtest/image.jpg\"}"}])

The function you want to call is documented here.

It gets the form:

HTTPoison.post(url, body, headers \\ [], options \\ [])

So the first argument shall be the URL, then the body, and then only the headers.

By writing HTTPoison.post(url=url, header=header), note that the url=url and header=header does not really have a meaning for what you're trying to achieve, simply write, when you have an empty body:

HTTPoison.post(url, "", header)

(As a matter of recommendation, I'd rename header to headers too if I were you)
