@austinvazquez Looks like the "configure AWS credentials" step got skipped in the e2e tests, so I don't think the credential helper ever actually got used. Did you at least do a smoke test manually?

[austinvazquez]

@pendo324, oh good catch. Let me manual test using a local build and update the description with the results.

@pendo324, updated description with testing. PTAL.
