Cannot add CIDR range to `aiven_transit_gateway_vpc_attachment`

[supergillis]

What happened?

Adding a CIDR block to an aiven_transit_gateway_vpc_attachment results in an error.

Terraform used the selected providers to generate the following execution plan.
Resource actions are indicated with the following symbols:
  ~ update in-place
Terraform will perform the following actions:
  # aiven_transit_gateway_vpc_attachment.network_iot-devops-aiven-iot-dev_aiven_320782F5 (network/iot-devops-aiven-iot-dev/aiven) will be updated in-place
  ~ resource "aiven_transit_gateway_vpc_attachment" "network_iot-devops-aiven-iot-dev_aiven_320782F5" {

What did you expect to happen?

I expected the CIDR range to be added to the VPC attachment.

What else do we need to know?

Aiven provider version: 4.8.0

Hey. Thanks for the reporting. Regarding to the version: please update to 4.8.2 as 4.8.0 might be unstable or defective.

[supergillis]

Will this fix be included in the next release?
