RESOLUTION

dynamic "backend" {

Module Version

2.0.6

Terraform version

1.6.0

Expected behavior

successful LB deployment.

Current behavior

can not deploy load balancer frontend because backend not in supported mode.

Anything else to add?

dynamic "backend" {
for_each = var.backends
content {
group = backend.value
failover = false
balancing_mode = "CONNECTION"
}
}

There was a change in the terraform-provider-google version 6.0 default values that now requires explicitly set balancing_mode.
We need to adjust the module to be used with the newer provider version.
