@ch1bo Here is the withoutProtocolUpdates error. https://github.com/input-output-hk/hydra/actions/runs/8161289799/job/22309727685?pr=1338#step:5:2151

@ch1bo Here is the withoutProtocolUpdates error. https://github.com/input-output-hk/hydra/actions/runs/8161289799/job/22309727685?pr=1338#step:5:2151

Protocol updates in the tx body seem to be bound only up to protocol version 8 (= babbage) as they (most likely) are done differently in conway (= protocol version 9)

Consequently, let's not clear that field (i.e. the updateTxBodyL) in the generator, but see whether the normal arbitrary transactions are fine within our tests. If not, we might need to tweak the generator to exclude any of the governance actions - the equivalents of protocol updates.
