rpc: WebSocket client cannot parse Tx events

[thomas-nguy]

This error occurs only with Ethermint message which add a log event there

https://github.com/tharsis/ethermint/blob/main/x/evm/keeper/msg_server.go#L58

The websocket is unable to receive the tx result. I am assuming it is related to deserialization.

I managed to narrowed down the issue to those line

https://github.com/informalsystems/tendermint-rs/blob/master/rpc/src/event.rs#L75
https://github.com/informalsystems/tendermint-rs/blob/master/tendermint/src/abci/tag.rs#L50

And if I remove

    #[serde(
        serialize_with = "base64string::serialize",
        deserialize_with = "base64string::deserialize_to_string"
    )]

from the tag's Values, then it fixes the issue (I can see the tx from websocket)

Any idea how this could be fixed in a clean way?

How can we reproduce this to confirm?

One way of testing this out (with more verbose logging) is to use our RPC CLI.

Hi @thanethomson

We decided to fix the issue on Ethermint side
