Ciao all,
I don't know exactly since when this error has been there but I see that there is the following problem and I don't know how to solve it.
Could you help me?

I did the installation via helm as indicated.
These two agents are trying to start on a local kubernetes cluster.
They were created yesterday January 8th when I tried to create from the rancher UI a kubernetes cluster on aws, I guess.
the error is given by the two agents on the local k8 cluster

Many thanks
