I'm trying to access AWS Aurora MYSQL from my Flutter App using the Amplify CLI in Android Studio according to these instructions;

https://docs.amplify.aws/cli/graphql-transformer/relational

Here are the steps I've taken;

amplify init
amplify add api
amplify api add-graphql-datasource 

After choosing "mycluster" as the "Aurora Serverless cluster that will be used as the data source for your API: "

I get this error;

"No RDS access credentials found in the AWS Secrect Manager.my "mycluster" Aurora Mysql database"

This happens no matter what default authorization type for the API I choose (IAM, API key, Cognito user pool, etc.)

Is this a bug? How should I Proceed?
