Failed to deserialize the empty key of storage proof in EIP1186ProofResponse (for Mainnet)

Description

Download the EIP1186ProofResponse data to deserialize:

curl https://eth.llamarpc.com \
  -X POST \
  -H "Content-Type: application/json" \
V  --data '{"method":"eth_getProof","params":["0x105dD0eF26b92a3698FD5AaaF688577B9Cafd970",["0"],"latest"],"id":1,"jsonrpc":"2.0"}' > tmp_proof_empty_key.json

# Unnecessary to format the JSON.
cat tmp_proof_empty_key.json | jq > proof_empty_key.json
cp proof_empty_key.json ethers-core/testdata/proof_empty_key.json

Edit ethers-core/testdata/proof_empty_key.json to delete JSON RPC header:

{
-   "jsonrpc": "2.0",
-   "id": 1,
-   "result": {
  "accountProof": [
...
-  }
}

Add this test cases to ethers-core/src/types/proof.rs:

#[test]
fn can_deserialize_proof_empty_key() {
    serde_json::from_str::<EIP1186ProofResponse>(include_str!(
        "../../testdata/proof_empty_key.json"
    ))
    .unwrap();
}

And run the test:

cargo test -- can_deserialize_proof_empty_key
