Unknow error on aws iot about aws-elixir

[RandomGuy2020]

I used the version 6. The input was wrong I had to:
input = %{policyDocument: test}
with test = Poison.encode!(%{
"Version": "2012-10-17",
"Statement": [
%{
"Effect": "Allow",
"Action": [
"iot:Publish",
"iot:Receive"
],
"Resource": [
"arn:aws:iot:us-west-2:000000000000:topic/topic_1",
"arn:aws:iot:us-west-2:000000000000:topic/topic_2"
]
},
%{
"Effect": "Allow",
"Action": [
"iot:Subscribe"
],
"Resource": [
"arn:aws:iot:us-west-2:000000000000:topicfilter/topic_1",
"arn:aws:iot:us-west-2:000000000000:topicfilter/topic_2"
]
},
%{
"Effect": "Allow",
"Action": [
"iot:Connect"
],
"Resource": [
"arn:aws:iot:us-west-2:000000000000:client/basicPubSub"
]
}
]
})

Hi, @RandomGuy2020! Thanks for opening the issue.
The input value is a policy like the one in the example: https://docs.aws.amazon.com/cli/latest/reference/iot/create-policy.html#examples

We are investigating how to improve our docs to include some examples like these.

[RandomGuy2020]

Thanks for you quick reply! I'm very sorry but i'm very bad and it doesn't work when you will have time could you see the code below and say to me what's is wrong ?
Here is the code (I replace the 000000000000 by my id account) :
`
client1 = initClient()

input = %{
"Version": "2012-10-17",
"Statement": [
    %{
        "Effect": "Allow",
        "Action": [
            "iot:Publish",
            "iot:Receive"
        ],
        "Resource": [
            "arn:aws:iot:us-west-2:000000000000:topic/topic_1",
            "arn:aws:iot:us-west-2:000000000000:topic/topic_2"
        ]
    },
    %{
        "Effect": "Allow",
        "Action": [
            "iot:Subscribe"
        ],
        "Resource": [
            "arn:aws:iot:us-west-2:000000000000:topicfilter/topic_1",
            "arn:aws:iot:us-west-2:000000000000:topicfilter/topic_2"
        ]
    },
    %{
        "Effect": "Allow",
        "Action": [
            "iot:Connect"
        ],
        "Resource": [
            "arn:aws:iot:us-west-2:000000000000:client/basicPubSub"
        ]
    }
]

}

AWS.IoT.create_policy(client1, "testelixir", input)

`

Thanks you for your time 😄

@RandomGuy2020 I think you need to send the input as a JSON string, because it won't be converted automatically. Can you give a try and check if works?

PS: you have Poison available, so you can encode as the docs suggest: https://github.com/devinus/poison#usage

[RandomGuy2020]

It doesn't work too when I use

input=Poison.encode!(...)

And the error is still {:error, nil}

[philss]

@RandomGuy2020 can you try to create the same policy using AWS console?
Also, do you see warnings when you try to create the policy?

[RandomGuy2020]

It's working on aws console and I don't have warning

[philss]

OK, thank you! One more try: would you mind to use the GitHub version and see if works?
Just change your mix.exs to point to this repository: {:aws, github: "aws-beam/aws-elixir"}.

[RandomGuy2020]

Ok now I have an error 400, when I let the Poison.encode!(..) I don't have a message for the error but when I remove it I always have an error 400 but the body error is : "message":"1 validation error detected: Value null at 'policyDocument' failed to satisfy constraint: Member must not be null"

[philss]

@RandomGuy2020 cool! We got something :D

I have an idea that is to use another HTTP client and log the request/response. Tesla has this middleware that logs the request, so we can use that to inspect what is going on. But the process of configuring another HTTP client is not documented yet (it was introduced in #42), so I will try to document it first.

[RandomGuy2020]

I want to add the get_policy doesnt work with {:aws, github: "aws-beam/aws-elixir"} they say : The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.
But it's working on the version 6

[tejpochiraju]

@RandomGuy2020 - I am getting the same error The request signature we calculated does not match the signature you provided. when calling AWS.IoT.list_things.

The client works fine for AWS.S3 queries. I have been trying a few versions of aws-elixir to see which one works but haven't been able to identify one yet. When you refer to version 6 do you mean the release 0.6.0?

I will open a new issue if your response does not resolve it.

[philss]

@tejpochiraju did you try the version from GitHub (the master branch)?
