IoT - shadow error

[ulutomaz]

Hi,

I am trying to get through the configuration of this package. To get to the point where I would be able to get and update the devices shadow, through the REST API. For easier development, I added my self a permission where I has access to all iot:* resources.

In my config/dev.exs I have a confguration like in Readme.md

iex> client = %AWS.Client{access_key_id: "<access-key-id>",
                     secret_access_key: "<secret-access-key>",
                     region: "us-east-1",
                     endpoint: "amazonaws.com"}

Then, if i issue a code to initialize this client, I get back response like

%AWS.Client{access_key_id: "<secret>", endpoint: "amazonaws.com",
 port: "443", proto: "https", region: "eu-west-1",
 secret_access_key: "<secret>", service: nil}

I can even issue a call to list all the things. I get back the result with all the things listed.

BUT: When I want to get back the shadow of one of the devices, I get back the error.

I call the shadow with

AWS.IoT.DataPlane.get_thing_shadow(Shadow.Client.init_client(), "<thingName>")

init_client is just my function... nothing special.
And I get back {:error, "Not Found"} though if I go and search it over the web console I can see it there.

I found the error. get_url inside iot_data.ex returns an url ending with a slash (/). If you remove the slash, everything works.

Before:

defp get_url(host, url, %{:proto => proto, :port => port}) do
  "#{proto}://#{host}:#{port}#{url}/"
end

After:

defp get_url(host, url, %{:proto => proto, :port => port}) do
  "#{proto}://#{host}:#{port}#{url}"
end
