Error creating yandex_ydb_table with TTL in months

[baznikin]

1. I cant create yandex_ydb_table with TTL in months (P2M).
2. However, if I change notation to days (P60D) table created.
3. Subsequent runs of terraform apply tries to change P2M in cloud on P60D as written in manifest.
4. If I change it to P2M there is no error (until I try to create new table with such manifest)

So, API accept only days notation, but store in internally in full ISO 8601 form.

resource "yandex_ydb_table" "outbound" {
  connection_string = yandex_ydb_database_serverless.this.ydb_full_endpoint
  path              = "${var.name}-table"
  primary_key       = ["event_id"]

  ttl {
    column_name     = "_timestamp"
    expire_interval = "P2M" # ISO 8601
  }

  column {
   # our columns here
  }
  column {
    name = "_timestamp"
    type = "Timestamp"
    not_null = false
  }
  column {
    name = "_partition"
    type = "String"
    not_null = false
  }
  column {
    name = "_offset"
    type = "Uint64"
    not_null = false
  }
  column {
    name = "_idx"
    type = "Uint32"
    not_null = false
  }
}
