Issue:
Summary: https://pkg.go.dev/log#Fatalf

Fatalf is equivalent to Printf() followed by a call to os.Exit(1).

The checklist before PR is ready for review:

• has unit testing for new added codes
• has functional testing for new added features
• has checked the lint or style issues
• README updated if need
