Hi @efeozyer,

Good morning.

Thanks for opening the issue. The error above is coming from the default credential resolution chain where SDK is unable to find the AWS credentials. The details could be found at Credential and profile resolution, where Amazon EC2 instance metadata is the last one to be resolved. Could you please share how you have configured your credentials? Simply configuring Cognito configuration would not work since you need to configure AWS credentials in order to use AWS services.

Thanks, Ashish

Hi @ashishdhingra, You're right, when I add accessKey and secretKey issue fixed. IMHO we should add this point readme.md or configuration sectio.

Thanks, Efe
