Hi tianyma,

It looks like this might be a bug in the version of garage you're using. Is it fixed if you use garage installed from master? That functions was renamed in #2170

[tianyma]

Yes, it seems a version problem, I used to release the version of tag v2021.03.0, it's ok when changed to master.
