• It appears that 'delegatedDomianName' is misspelled. Consider renaming it to 'delegatedDomainName' for clarity.

delegatedDomianName := os.Getenv("HW_ASSUME_ROLE_DOMAIN_NAME")

[Copilot]

When conversion of HW_ASSUME_ROLE_DURATION fails, the code logs an error and defaults to 0. Consider adding validation or a more descriptive error handling approach if 0 is not an acceptable duration.
