There was a problem hiding this comment.
Can somebody from the node cli team take care of this? There are more type errors because of this change.

Visible changes: * IntersectMBO/cardano-ledger#1993 * IntersectMBO/cardano-ledger#2021 One of the changes in Allegra over Shelley is the notion of transaction auxiliary data. We retrospectively define tx metadata to be part of the auxiliary data where in the Shelley era this consists only of the existing tx metadata. But from the Allegra era the auxiliary data contains both the tx metadata and also auxiliary scripts. So where we previously hashed the tx metadata, we now hash the auxiliary data. Take the opportunity to refactor the tx metadata representation and conversion functions to fit better with the new scheme. Also take the opportunity to tidy up the imports in the Query module since we have some very similarly-named type classes. Co-authored-by: Duncan Coutts <duncan@well-typed.com>
Doing a number of TODOs. The tests were generating invalid tx bodies, e.g. with negative tx outs, which ought to be caught by the validation in the API rather than in the ledger serialisation. This does not yet adjust the generators to make only valid tx bodies.
