AWS Java SDK error: Unable to load credentials from any of the providers

Question

I'm writing a test to see if I can access credentials stored in AWS secrets manager, in Java on my local machine.

I've tested that I have an active session on my machine by running the aws sts get-caller-identity command as suggested in the aws docs here.

I even ran the command aws secretsmanager get-secret-value --secret-id some-id in intelliJ's terminal to check if I could retrieve the secret value and I was successful.

However when I attempt to get the value using the AWS SDK

var client = SecretsManagerClient.builder()
        .region(Region.of(region))
        .build();

var getSecretValueRequest = GetSecretValueRequest.builder()
        .secretId(secretName)
        .build();

var getSecretValueResponse = client.getSecretValue(getSecretValueRequest); 

It fails with the error:

software.amazon.awssdk.core.exception.SdkClientException: Unable to load credentials from any of the providers in the chain AwsCredentialsProviderChain(credentialsProviders=[SystemPropertyCredentialsProvider(), EnvironmentVariableCredentialsProvider(), WebIdentityTokenCredentialsProvider(), ProfileCredentialsProvider(profileName=default, profileFile=ProfileFile(profilesAndSectionsMap=[{default=Profile(name=default, properties=[output, sso_session, aws_access_key_id, aws_secret_access_key, region, sso_role_name, sso_account_id])}, {my-sso=Profile(name=my-sso, properties=[sso_region, sso_start_url, sso_registration_scopes])}])), ContainerCredentialsProvider(), InstanceProfileCredentialsProvider()]) : [SystemPropertyCredentialsProvider(): Unable to load credentials from system settings.
