Describe the Problem

prestateTracer is working fine with debug_traceCall.
But it seems diffMode: true is not working properly.
The diff mode should return the differences between the transaction’s pre and post-state, but it acts like prestate mode with diff mode.

Code Snippet

const transaction = await provider.send(
                "debug_traceCall", [
                {
                    "from": res.from,
                    "to": res.to,
                    "data": res.data,
                },
                "latest",
                {tracer: "prestateTracer", tracerConfig: {diffMode: "true"}},
            ]);

This isn’t anything ethers performs any additional processing to. The .send is a low-level API designed to interact directly with an Ethereum node, so you would need to check with your nodes documentation, I think.

Sorry I can’t help more.
