Describe the bug

We ran into an error on Lambda when we bumped up our credential-providers package to 3.730.0.

Thanks for submitting this report. I am investigating this issue.

As a workaround, please use 3.729.0, or provide credentials like this:

import { PublishCommand, SNSClient } from "@aws-sdk/client-sns";
import { fromTemporaryCredentials, fromNodeProviderChain } from "@aws-sdk/credential-providers";

const sns = new SNSClient({
  region: "ap-southeast-2",
  credentials: fromTemporaryCredentials({
    params: {
      RoleArn: "arn:aws:iam::000000000000:role/some-role",
      RoleSessionName: "some-session",
    },
    masterCredentials: fromNodeProviderChain()
  }),
});
