The correct name for this field is 'input' according to the Ethereum specs [0]. However, for the longest time, clients have been using 'data' and servers have been lenient to accept both, preferring 'input' over 'data' when both appear. Our lack of support for 'input' had gone unnoticed until go-ethereum decided to adjust their ethclient implementation to issue eth_call and eth_estimateGas requests with the 'input' field instead of 'data' [1]. This suddenly broke apps using this client against Lotus' Eth API.

I tried, but there doesn't appear to be a way to specify custom json. That's why I'm testing this at the encoding layer instead of in the integration tests. |

Yes. It's setting params.EthCallRaw.Data to params.Input, if set. Then, below, we return params.EthCallRaw.
