Unable to run haystack model with sagemaker

Hi, I need to deploy Haystack model for question answering system. I followed below tutorial, but it is failing while making the session with sagemaker. I am getting below error

https://github.com/deepset-ai/haystack-sagemaker

provide custom invocation layer for jumpstart-dft-hf-llm-falcon-40b-instruct-bf16 by subclassing PromptModelInvocationLayer

Please help if someone has any idea about this.
