AWS_PROFILE no longer works in v3

[simov]

Describe the bug

Using AWS_PROFILE no longer works in aws-sdk v3 (might be related to this one #1193).

I understand that in v3 the STS module is no longer part of the core SDK, but even after including @aws-sdk/client-sts in my project, using AWS_PROFILE still throws the following error:

(node:2519) UnhandledPromiseRejectionWarning: Error: Profile the-profile requires a role to be assumed, but no role assumption callback was provided.

Nothing else changed on my end besides updating the require statements in my project to use the v3 ones and remove .promise() on all API calls.

Your environment

SDK version number

"@aws-sdk/client-kms": "^3.4.1",
"@aws-sdk/client-sts": "^3.4.1"

Is the issue in the browser/Node.js/ReactNative?

Steps to reproduce

Please share code or minimal repo, and steps to reproduce the behavior.

You can probably have an empty file and it's still going to throw the above error because that happens before executing your actual code. I can share an example if needed.

Hi @simov This is indeed duplicated with #1193. I will label this issue duplicate and I will post the latest progress on the other ticket. Please feel free to provide more comment on that issue too.
