debug_traceTransaction fails: required historical state unavailable

[wjmelements]

Thanks for this project. I hope I can get it to work.

I have gotten two different errors with two different nodes. I suspect the underlying issue is that debug is not supported by geth without --gcmode "archive". I am currently testing this by resyncing my node as an archive node.

From INFURA the error was

Error: Invalid JSON RPC response: ""

From my own node the error was

I estimate the archive node will finish syncing by the end of next week.

Thanks for reporting the issue! If profiling a live real-world tx is not absolutely necessary, I recommend running geth in dev mode to avoid syncing.
