Testing flagger occurs TrafficSplit create error

[freeNestor]

I'm newbie here. We're testing Blue/Green release with flagger and linkerd on kubernetes, but never make it (have not yet tried other like canary, nor A/B testing). Described on canary there's a warning below, not sure if this relates, and we tried trafficsplit v1alpha2/v1alpha3/v1alpha4 with no luck. flagger TrafficSplit rpcdemo-client.linkerd-demo create error: the server could not find the requested resource (post trafficsplits.split.smi-spec.io)

Anyone can help? If need I can provide more info, thanks.

Expected behavior

route traffic to new version.

Additional context

• Flagger version: 1.21.0
• Kubernetes version: 1.22.1
• Service Mesh provider: linkerd 2.11
• Ingress provider: nginx controller 1.0.4
