Summary
On a node with preliminary Conway support, I can't get to era with Babbage protocol version 8.
The issue happens only on local cluster that updates to PV8 using update proposal. Local cluster that uses TestBabbageHardForkAtEpoch works ok.

It doesn't make any difference if I set TestEnableDevelopmentHardForkEras to true or not. There is a difference in behavior depending on TestEnableDevelopmentNetworkProtocols settings.

With TestEnableDevelopmentNetworkProtocols: true, I can reach epoch where protocol version is supposed to be set to 8, but have following issue:

cardano-cli query protocol-parameters --testnet-magic 42
Command failed: query protocol-parameters   Error: Consensus mode and era mismatch. Consensus mode: CardanoMode Era: ConwayEra

Without TestEnableDevelopmentNetworkProtocols: true, after reaching the epoch where protocol version is supposed to be set to 8, no more blocks are produced and the chain is not progressing. I have following errors in log files:

[bender-3:cardano.node.ErrorPolicy:Error:59] [2023-03-13 11:18:42.70 UTC] IP 127.0.0.1:41449 ErrorPolicyUnhandledApplicationException (HardForkEncoderDisabledEra (SingleEraInfo {singleEraName = "Conway"}))
