The issue is to bump the aeson dependency version to satisfy the stackage integration checklist linked in the description (https://github.com/commercialhaskell/stackage/issues/5393). First, review the linked stackage issue to identify the required aeson version or constraints. Then examine the servant repository's cabal or stack.yaml files to see the current aeson version and update it accordingly. Ensure that the updated version is compatible with the rest of the dependencies and that the project builds successfully. No existing PR or assignee indicates availability.
