traceReplayBlockTransactions does not work at block 0 #17

Closed ankitchiplunkar closed 6 years ago

ankitchiplunkar commented 6 years ago

Describe the bug traceReplayBlockTransactions does not work at block 0. This is due to an error in Parity https://github.com/paritytech/parity/issues/8762

To Reproduce With an archive parity node run the command

ether_sql --settings=PersonalParitySettings scrape_block --block_number=0

See error

Expected behavior Either the parity needs to be able to run the above command at block 0 or ether_sql needs to skip trace and stateDiff calculation at block 0
