https://github.com/aws-samples/amazon-bedrock-workshop/blob/main/02_Summarization/02.long-text-summarization-titan.ipynb When I run below code

modelId = "amazon.titan-tg1-large"
output = ""
try:

    output = summary_chain.run(docs)

except ValueError as error:
    if  "AccessDeniedException" in str(error):
        print(f"\x1b[41m{error}\
        \nTo troubeshoot this issue please refer to the following resources.\

         \nhttps://docs.aws.amazon.com/bedrock/latest/userguide/security-iam.html\x1b[0m\n")      
        class StopExecution(ValueError):
            def _render_traceback_(self):
                pass
        raise StopExecution        
    else:
        raise error```

getting following error. (model id is : modelId = "amazon.titan-tg1-large")

Titan examples are not working at the moment. The model is still in preview: https://github.com/aws-samples/amazon-bedrock-workshop/issues/71
