"An internal error has occurred" when attaching Directory Service to RDS in the Zurich region (eu-central-2).

Hi everyone, When I try to create SQL server RDS with Microsoft SQL Server Windows Authentication setting: I receive the error below:

When I look at Directory Service in eu-central-2, I also see 3 application and services avaiable for Directory:

Compare with eu-central-1, it seems to lack "Amazon RDS for SQL Server".

I also attached the log when I try to attach Directory Service to the RDS instance in eu-central-2 region using the next command:

aws --profile <info> --region eu-central-2 rds modify-db-instance \
   --db-instance-identifier <info>  \
   --domain <d-c...info> \
   --domain-iam-role-name rds-directoryservice-access-role \
  --apply-immediately

The log content:
