Welcome! Please see the About page for a little more info on how this works.
I'm trying to connect with the datomic cloud, but when I connect with the client I get the following error: Execution error (NoClassDefFoundError) at com.amazonaws.services.s3.AmazonS3ClientBuilder/standard (AmazonS3ClientBuilder.java:46). Could not initialize class com.amazonaws.services.s3.S3CredentialsProviderChain
This error indicates that you do not have the sourced AWS credentials to connect to the AWS account you are running Cloud in.
