Invalid tracer argument on debug_traceTransaction

[mpauls2839]

I'm seeing the debug_traceTransaction method consistently fail across different node providers. Specifically, I believe it may be related to the provided tracer argument.
{ "jsonrpc": "2.0", "id": 2, "error": { "code": -32602, "message": "invalid 2nd argument: options 'tracer': invalid tracer value" } }

Hey @mpauls2839,
Is this related to ethtx? If so, can you give more details? Transaction hash, the provider you are using, etc?
Regards

Yes, I believe this is failing on the ethtx call to debug_traceTransaction. I've tried both quicknode and Alchemy.com as my node providers. It seems to fail on any transaction, but here's a sample one: 0xe8cc27de3feb65a0403d2f2f772e74db2e8ded12f5f6343b75005894b3820817

Here's a screenshot of the call failing. It seems all other calls are successful however.

Specifically, I believe this error is happening in ethtx/providers/web3_provider.py::line 257

@mpauls2839,
thanks. Are you using free plans from these providers? A full archive node is required for ethtx to work, probably getblock.io for the last 64 blocks has this functionality (for free), otherwise, you need a higher plan.
Let me know and I will check it out more deeply 🙌
