Getting unknown parameter, image, when using bedrock-runtime in Lambda.

[wvabrinskas]

I have a properly setup Guardrail in AWS that uses image filtering (I understand it's in beta right now). Below is a snippet from my lambda function that shows the apply_guardrail call. I'm getting an unknown parameter error, which is weird because I know this function supports image in the content block according to the documentation.

I have tried replacing the image_bytes with a static string as well and that didn't work.

I'm wondering what my issue is with this request. I'm at a dead end.

Request

    s3_client = boto3.client('s3')
    bedrock_client = boto3.client('bedrock-runtime')
  
    # other irrelevant setup code

    response = s3_client.get_object(Bucket=bucket, Key=key)
    image_content = response['Body'].read()

    image_bytes = convert_image_to_base64(image_content)

    inner_content = {
        "image": {
            "format": "jpeg",
            "source": {
                "bytes": image_bytes
            }
        }
    }
    
    # Apply guardrail to the image
    guardrail_response = bedrock_client.apply_guardrail(
        guardrailIdentifier="some_id",
        guardrailVersion="Version 1",
        source="INPUT", 
        content=[
            inner_content       
        ]
    )

  ]
}

Turns out I need to setup a dependency zip to deploy with my function. lambda has an out of date install.
