Same happens to me when trying to create a db in ANY RDBMS. I've tried MariaDb, Sql Server.
For those who are suffering because of this error and lack of response of a tech person, you need to create the VPC first with corresponding subnets and at least two availability zones, then select that VPC when creating the DB. The error is reproducible if you want the RDS wizard to create the VPC and subnets automatically.
