I have HA proxy ingress in Kubernetes AKS. After upgrading Kubernetes version, I get errors from HA proxy. I tried to solve the problem modifying my old haproxy.yaml to avoid deprecated API's and to get the latest image of HA proxy ingress. But the error persist. How can I fix the errors?.

I also tried this answer, but it doesn't work for me.

I checked this issue on github, but despite I use v0.12-snapshot.3 the error persist.

This is my modified haproxy.yaml:
