DBaaS PostgreSQL unable to migrate from flavor {...} to flavor_id

[legioner0]

I have selectel_dbaas_postgresql_datastore_v1 cluster with flavor {...} block. For some reason I had to migrate to fixed configuration with known flavor_id. On second apply terraform fails on validation in API call.

Terraform Version

Terraform v1.9.7

Terraform Provider Selectel Version

5.4.0

Affected Resource(s)

• at least selectel_dbaas_postgresql_datastore_v1

Terraform Configuration Files

Initial:

resource "selectel_dbaas_postgresql_datastore_v1" "datastore" {
    name        = "test1"
    node_count  = 1
    project_id  = "<sensitive value>"
    region      = "ru-2"
    subnet_id   = "<...>"
    type_id     = "b15e73d3-e585-4b6c-bc95-0b698de8f771" # PostgreSQL 14

    flavor {
        disk  = 32
        ram   = 4096
        vcpus = 1
       }

    pooler {
        mode = "transaction"
        size = 50
       }
   }

Edited:

resource "selectel_dbaas_postgresql_datastore_v1" "datastore" {
    name        = "test1"
    node_count  = 1
    project_id  = "<sensitive value>"
    region      = "ru-2"
    subnet_id   = "<...>"
    type_id     = "b15e73d3-e585-4b6c-bc95-0b698de8f771" # PostgreSQL 14

    flavor_id= "c41d8095-65bd-48d9-a5b6-2fa3c2ba064a"
    pooler {
        mode = "transaction"
        size = 50
       }
   }

Expected Behavior

changes applied without error

Actual Behavior

Second apply fail on validation in API call:

│ Error: error updating datastore '...': Bad Request: Validation failure: Only one of flavor or flavor_id may be specified. Code: 400

Steps to Reproduce

1. terraform apply
2. replace flavor {...} with flavor_id
3. terraform apply
