Motivation

As reported by #12448, we had an issue with the JS AWS SDK v3 accepting some conditions that shouldn't have been accepted. This is because we skipped validating the request if the request did not have a policy field, lower-cased. But the JS SDK sends it as Policy.

The Gist sent by the user now works with the fix, and an AWS validated fix asserts that this is the right behavior.

Changes

  • update the logic to be case insensitive while validating certain fields of the Post request
