Internal error when querying certain blocks #495

Closed infsaulo closed 4 weeks ago

infsaulo commented 1 month ago

Problem

Whether this is intermittent or not, there are blocks that cannot be retrieved from testnet endpoint. E.g. block with height 813 cannot be retrieved using eth_getBlockByNumber RPC endpoint.

Steps to Reproduce

m-Peter commented 1 month ago

This seems to be some kind of regression, I get this error for non-empty blocks:

curl -s https://testnet.evm.nodes.onflow.org -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["0x9d7", false],"id":1}' | jq
{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32000,
    "message": "internal error"
  }
}

But for empty blocks:

curl -s https://testnet.evm.nodes.onflow.org -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["0x9d6", false],"id":1}' | jq

}

It seems to work.

@sideninja Most likely related to the removal of https://github.com/onflow/flow-evm-gateway/pull/485. I checked by connecting a local EVM Gateway instance to testnet, but I don't get the same error. Could you check the logs?

sideninja commented 4 weeks ago

I believe there's a single block (would have to double-check but the one specified above) that is corrupted due to type migration. I do plan to reindex and it should fix it.

sideninja commented 4 weeks ago

@infsaulo the problem should be resolved now. Thank you for flagging.

Closing the issue.
