The project makes use of aws-sdk JavaScript project which is entering maintenance mode and is deprecated.
It looks like there is a new V3, but switching over is a bit more involved (as loading credentials is not done in the same way as in V2).
Creating this issue as the SDK is logging a deprecation notice which is triggering an alert:
ERROR (pod: mevblocker-dune-5cd74d8b46-hml2l):
(node:30) NOTE: We are formalizing our plans to enter AWS SDK for JavaScript (v2) into maintenance mode in 2023.
