@yunks128 Looks good, thanks for your contribution.

@yunks128 can you fix the static analysis failure?

[drewm-swe]

It appears there is still a trailing whitespace issue with the static analysis.

@drewm-jpl, the trailing whitespace issue is fixed, but another error remains. I don't see "--no-fail-on-changed" anywhere, but the error is there. Do you have any idea? Thanks.
