geth tests fail with geth 1.15.3, waiting for a fix in py-geth

[banteg]

Issue Description

Geth tests are currently failing when using Geth 1.15.3+ because the genesis configuration requires a blobSchedule field for the Cancun fork.

Error Message

geth.exceptions.PyGethValueError: Error initializing genesis.json: 
    stdout=Fatal: Failed to write genesis block: invalid chain configuration: missing entry for fork "cancun" in blobSchedule

    stderr=INFO [02-26|09:26:08.653] Maximum peer count                       ETH=50 total=50
INFO [02-26|09:26:08.659] Set global gas cap                       cap=50,000,000
INFO [02-26|09:26:08.659] Initializing the KZG library             backend=gokzg

Root Cause

Recent Geth versions (1.15.3+) require a blobSchedule field in the genesis configuration to support the Cancun fork's blob transactions. This field is required to initialize a local development chain.

Solution Status

There is an open PR in the py-geth repository that addresses this issue:
ethereum/py-geth#251

Once this PR is merged and a new py-geth version is released, Ape will need to update its dependency to fix the Geth tests.

Impact

This issue affects all tests that rely on the Geth provider, including tests/functional/geth/test_chain.py.

Thanks! I was having the same issue, but I thought it was my setup which was messed up. 😅
Looking forward to this fix. 👀
