Bytes base64 deserialization

[fmorency]

Using tendermint-rs v0.28.0

Base64 deserialization on Bytes, e.g.,

// rpc/src/endpoint/broadcast/tx_sync.rs
pub struct Response {
...
  #[serde(with = "serializers::bytes::base64string")]
  pub data: Bytes,
...
}

doesn't work properly.

The following transaction is being executed.

ResponseDeliverTx { 
  code: 0, 
  data: b"\xd9'\x12\xa3\x02\xd9'\x10X\x1d\x01J\x10\x1dR\x1d\x81\x02\x11\xa0\xc64k\xa8\x9b\xd1\xcc\x1f\x82\x1c\x03\xb9i\xff\x9d\\\x8b/Y\x04A\xf6\x05\xc1\0", 
...
}

where the hexadecimal string corresponding to data is d92712a302d92710581d014a101d521d810211a0c6346ba89bd1cc1f821c03b969ff9d5c8b2f590441f605c100.

However, I get the following response when executing self.client.tx(tendermint::Hash::Sha256(hash), false).await

Response { 
  hash: Hash::Sha256(E35B544830279AE45AD4D5225C67C2BD2AECDCE25B1685CEA3767F0E8331882D), 
  ...
  tx_result: DeliverTx { 
    code: Ok, 
    data: b"2ScSowLZJxBYHQFKEB1SHYECEaDGNGuom9HMH4IcA7lp/51ciy9ZBEH2BcEA", 
    ...
  }
  ...
}

The data field is still base64-encoded.

echo 2ScSowLZJxBYHQFKEB1SHYECEaDGNGuom9HMH4IcA7lp/51ciy9ZBEH2BcEA | base64 -d | xxd -p
d92712a302d92710581d014a101d521d810211a0c6346ba89bd1cc1f821c03b969ff9d5c8b2f590441f605c100
