Dependencies

 [com.cognitect.aws/api "0.8.692"]

Description with failing test case

I am trying to InvokeAgent using the following code:

(def bedrock-client (aws/client {:api :bedrock-agent-runtime}))
(let [request {:agentId "QWERTY"
                 :agentAliasId "QWERTY"
                 :sessionId "123456789"
                 :inputText prompt}
        response (aws/invoke bedrock-client
                             {:op :InvokeAgent
                              :request request})]
    response)

Thanks for logging this. I think this should be resolved with the latest version (871.2.29.35, just released) of the bedrock and endpoints artifacts. I'll leave this issue open for the time being just in case. My teammate has managed to reproduce this issue even with the newest bedrock artifact 871.2.29.35. We are investigating...

The InvokeAgent operation is a streaming operation (that yields a response with content type application/vnd.amazon.eventstream), and aws-api doesn't support streaming operations (we don't know how to decode an Amazon Event stream payload).
