our keeper data is not available, waiting for it to appear

[tirelibirefe]

Hello;
I've a bare-metal Kubernetes 1.18 and attempted to install stolon but it gives me following error:

2020-04-11T13:31:58.388Z INFO cmd/keeper.go:976 our keeper data is not available, waiting for it to appear 2020-04-11T13:31:58.461Z ERROR cmd/keeper.go:778 failed to update keeper info {"error": "update failed: failed to get latest version of pod: v1.Pod.ObjectMeta: v1.ObjectMeta.readObjectFieldAsBytes: expect : after object field, but found u, error found in #10 byte of ...|:{},\"k:{\\\"uid\\\":\\\"e0|..., bigger context ...|on-cluster\":{}},\"f:ownerReferences\":{\".\":{},\"k:{\\\"uid\\\":\\\"e0956964-6d30-4afb-97dc-1d0ae4500447\\\"}\":{|..."}

I've seen many people have faced with the problem but I couldn't have found any solutions.
Is there a way to acomplish installation or a planned project to make it run?

Thanks & Regards
