Confirmed this is an issue, but unfortunately the only solution is to either pass in a specific block head to fork from (ex: --fork-at 7000000) or wait until the upstream zksync-era repo has been updated with the latest Version14.

Such approach causes the same result with Version14
era_test_node fork mainnet --fork-at 13800000

The cutoff seems to the block 13234790. Anything above it will fail.

any updates or fix on this?

[MexicanAce]

@AaronNan24 We're still waiting on an upstream change to be pushed to zksync-era. Once that's merged, this PR should address the problem: #111

[AaronNan24]

Thx ur efforts! @MexicanAce

Would like to know how to use it ahead of time, can I build it locally to use? or is there any way to replay an existing transaction. I did use zkcast, but it also had problems, so I failed

wanted to look at the existing transactions to troubleshoot the code issue, thank you very much for your generous assistance!

[MexicanAce]

Unfortunately there's no work around until zksync-era is updated with the latest code running in Testnet/Mainnet. This is expected to happen before the end of the week.

[AaronNan24]

appreciate ur quick reply and explanation! and thanks again for all your hard work and shoutout to you guys

[MexicanAce]

This has been resolved with the latest Release and #111
