    messages=messages,
    inferenceConfig={
        "maxTokens": kwargs.get('max_tokens', 100),
        "temperature": kwargs.get('temperature', .5),
        "topP": kwargs.get('topP', 0.9),

looks like this issue only happens when the supplied image is a jpeg - if the input is converted to a png the converse operation works as expected
