We need to add validation here. Like https://github.com/aws/sagemaker-hyperpod-cli/blob/main/src/hyperpod_cli/utils.py#L124

[zhaoqizqwang]

Added validation in new commit

[zhaoqizqwang]

Per review from security guardian, failure in generating cloudwatch link would lead to system exit

sys.exit(
    f"Unexpected error happens when trying to get logs for training job {job_name} : {e}"
)

I'm adding a new try-except block for CW link creation. If there's any failure we skip and continue

[zhaoqizqwang]

Added try except for CW link creation. Manually raised error in the creation process and error message can be loaded correctly
