As this StackOverflow answer implies, this is needed for golang >=1.17

@yuting-fan @Yangtao-Hua , this is a mechanical change that fixes the error in the makefile's default target. It would be great if you could take any action on this issue, even if to only comment that you're looking at it.

Hi @skwashd
Thank you for the PR and it is really helpful. We noticed this issue, verified it happens when build with the new golang version. Related engineer is tracking and working on the fix, will release it after a through test.

Thanks,
Yangtao
