SNS publish issue with CredentialsProviderError #2659
Description
We're writing code in TypeScript v4.3.2, running NodeJs v14 and using "@aws-sdk/client-sns": "3.20.0".
We're able to publish messages for a while, sometimes days, sometimes hours and then we start receiving the following error message out of the blue:
error: {"tryNextLink":false,"name":"CredentialsProviderError","$metadata":{"attempts":1,"totalRetryDelay":0}}
message: Could not load credentials from any providers
metadata: { [-]
attempts: 1
totalRetryDelay: 0
}
name: CredentialsProviderError
stack: CredentialsProviderError: Could not load credentials from any providers

}
We create our SNSClient as follows and it's created once, when the service starts up.
this.snsClient = new SNSClient({ region: 'us-west-2' });
To publish we have a method that we call with this code:
return this.snsClient
.send(new PublishCommand(params))
.then(response => {
this.logger.log(Sent mid: ${response.MessageId});
return true;
})
.catch(error => {
this.logger.error(error);
return false;
});
We're running inside K8s and restarting the pod resolves the issue although it would be nice to make this issue go away altogether, which is the goal of thread. We're only publishing a few hundred messages a day.
