feat(evm): failed wasm precompile transaction don't propagate error message

Open matthiasmatt opened this issue 1 year ago • 5 comments

I had an error when creating a transaction for the wasm pre-compile (which came to a contract error in wasm). When querying the evm transaction, i just get failed true with no logs attached.

❯ curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"debug_traceTransaction","params":["0xd7371d317b2b62591225ecbb852e6a9206a60078f946cdc4311ab04d54f99b10"],"id":1}' http://localhost:8545
{"jsonrpc":"2.0","id":1,"result":{"failed":true,"gas":30000000,"returnValue":"","structLogs":[]}}

The only way i was able to see the error was with this debug print:

	data, err := p.Wasm.Execute(ctx, wasmContract, nibiruCaller, msgArgsBz, funds)
	if err != nil {
		fmt.Printf("Wasm execution failed: %v\n", err)
		return
	}

Can be replicated on SAI by setting the value on this branch from 2_000_000 to 200_000 for the gas limit.

TLDR; works as expected

Use debug_traceTransaction call to get error details.

ethers.js script to debug tx

const trace = await provider.send(
    'debug_traceTransaction', [
        tx.hash,
        {
            // Use callTracer for better visibility into the call stack
            tracer: 'callTracer',
            // Include return data to see error messages
            enableReturnData: true
        }
    ]);
console.log(JSON.stringify(trace, null, 2));

Proper flow (for apps):

  1. Send tx (eth_sendRawTransaction) -> returns tx hash
  2. Wait for tx (eth_getTransactionReceipt )
  3. If tx failed, call debug_traceTransaction to get error details.

debug_traceTransaction was empty for me when running out of gas during wasm precompile operation:

❯ curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"debug_traceTransaction","params":["0xd7371d317b2b62591225ecbb852e6a9206a60078f946cdc4311ab04d54f99b10"],"id":1}' http://localhost:8545


{"jsonrpc":"2.0","id":1,"result":{"failed":true,"gas":30000000,"returnValue":"","structLogs":[]}}

This is the log from 2 different txs from my local node:

  • First, a tx with not enough gas
  • Second, a tx with wrong msg
