Clojurians Log v2

error sounds like xml stuff landing where json expected, wonder if kinesis-video-media wire format is supported via aws-api 😬

sometimes hard to cook one up, but maybe a small reproducible example would help

Sure, perhaps you will see what I am missing. The aws-cli command works fine.

aws kinesis-video-media get-media --stream-arn "arn:aws:kinesisvideo:eu-west-1:9000ACCOUNT:stream/camera1/1607464961761" --start-selector StartSelectorType="NOW" --p devpl2 --endpoint-url "<https://s000.kinesisvideo.eu-west-1.amazonaws.com>" cam.mkv

I am able to invoke on the :kinesisvideo client and get Endpoint and StreamArn without any issues. To read from the stream I am creating a :kinesis-video-media client, which is created fine.

(def kvmedia (aws/client {:api :kinesis-video-media :region "eu-west-1" :endpoint kvs-endpoint :credentials-provider (cred/profile-credentials-provider "devpl2")}))

What breaks is invoke on the :kinesis-video-media client. Whatever I invoke with results in the cryptic json error.

(aws/invoke kvmedia {:op :GetMedia 
    :request {:StartSelector {:StartSelectorType "EARLIEST"}
                               :StreamARN stream-arn}})

The json error is in the thread. I even found the boto3 api for :kinesis-video-media and it seems like I am doing things in the same way.

Just guessing here - since it starts with < - that means you're getting an XML/HTML response?

You can bump logging level of the underlying http client and see if that helps
