How to create a config.json after saving a model

Folks,
I am trying out the code at GitHub - aws-samples/aws-inferentia-huggingface-workshop: CMP314 Optimizing NLP models with Amazon EC2 Inf1 instances in Amazon Sagemaker .

For inferentia instance, I get a config.json not found in the cloudwatch logs and inference fails. The config.json file is present in the traced model tar.gz file for inferentia.
Please help me resolve this.
Thanks
Ajay

P.S the log message — W-9002-model_1-stdout MODEL_LOG - OSError: file /home/model-server/tmp/models/cb9491669c1f44c1a0763e8a62d9368e/config.json not found
