I’ve solved this problem by upgating golang to v1.17. Not sure whether it is a bug for v1.16 or not.
Same issue here, trying to bump golang version, but it causes massive refactor to lots of other components.
Any alternative options?
reflect.StructFieldwas added in go 1.17. If you are using it and compiling with an earlier version of go, you will have a bad time.Edit:
MR #639 introduced a new version of
sigs.k8s.io/json. That version requires go v1.17. That MR did bump the go version forcontroller-toolsto v1.17. But, it looks like that change wasn’t “documented” anywhere, so it’s easy to understand why nobody knew that they needed to move to a newer version of go.
