error CONNECTION balancing mode is not supported for protocol HTTP, invalid about gke-autoneg-controller

[rosmo]

This seems to be coming from the API so I don't think it's an Autoneg issue. Also I don't believe we support the zones annotation. You have two types of backend services, global and regional (regional being used when you specify region in the annotation) and they come with various limitations with regards to load balancing modes.

With or without the region, I have the same issue. Even if I use the given parameters in the README.md from this repo, I have the same error about balancing :( I don't understand where the issue is.
Thanks !

Can you show me what kind of load balancer was set up and how?

[pburgisser]

I deployed the LB using this example (I used the exact same code):
https://github.com/terraform-google-modules/terraform-google-lb-http/tree/v7.0.0/modules/dynamic_backends

[rosmo]

Can you try this annotation:

  controller.autoneg.dev/neg: '{"backend_services":{"80":[{"name":"gke-development-ingress-backend-web"],"rate":100}}'

[pburgisser]

oh my bad, I used that example: https://github.com/terraform-google-modules/terraform-google-lb-http/tree/v7.0.0/examples/dynamic-backend.
Will try your advice, thanks

Still the same issue :(

Here is the annotations:

    cloud.google.com/neg-status: '{"network_endpoint_groups":{"80":"k8s1-c278397d-traefik-traefik-80-230eaa9a"},"zones":["us-central1-b","us-central1-c"]}'

Also, am I supposed to see something appearing on loadbalancer ?

[rosmo]

Instead of rate, use max_rate_per_endpoint.
