could not update upstreams after we create an api

[thayagapriyan]

resource "anypoint_api_instance" "weighted_routing" {
environment_id = var.environment_id
gateway_id = var.gateway_id
instance_label = "weighted-routing-demo"

spec = {
asset_id = "my-api"
group_id = var.organization_id
version = "1.0.0"
}

endpoint = {
base_path = "weightedRouting"
}

routing = [
{
label = "canary"
upstreams = [
{
weight = 90
uri = "http://backend-stable.internal:8080"
label = "stable"
},
{
weight = 10
uri = "http://backend-canary.internal:8080"
label = "canary"
}
]
}
]
}

if i run apply after making some changes in upstreams , it would throw error

Terraform will perform the following actions:

anypoint_api_instance.terraform_demo will be updated in-place

~ resource "anypoint_api_instance" "terraform_demo" {
id = "20938007"
~ routing = [
~ {
~ upstreams = [
~ {
~ uri = "http://backend-canary.internal:8080" -> "http://backend-canary.internal:8090"
# (2 unchanged attributes hidden)
},
# (1 unchanged element hidden)
]
# (1 unchanged attribute hidden)
},
]
# (12 unchanged attributes hidden)
}
