Problem: Error in querying block_results of blocks with slashing occurs

[calvinaco]

If a block contains a slashing events, the block_results RPC will return the error

{
  "jsonrpc": "2.0",
  "id": -1,
  "error": {
    "code": -32603,
    "message": "Internal error",
    "data": "error marshalling response: cannot encode unregistered type crypto.PublicKey_Ed25519"
  }
}

maybe updating SDK -- there were some PRs e.g. cosmos/cosmos-sdk#7147 ?

[leejw51crypto]

yes, it looks old version bug,
New version will display correctly.

[tomtau]

verified this on the latest master -- bdf5312

I'll try updating SDK once more, as there is some other patch:
cosmos/cosmos-sdk@91ca8ad

[tomtau]

updated sdk -- still the same.
I opened this issue cosmos/cosmos-sdk#7401

@calvinaco it's not only slashing -- also if you delegate (or change the voting power anyhow), it's the same

[leejw51crypto]

is it the same with protobuf?

[tomtau]

is it the same with protobuf?

I haven't found the exact block_results equivalent in gRPC -- one can "compose" it though, as gRPC exposes different module query interfaces (that are taken from block_results)

@calvinaco FYI, this is now fixed in Tendermint master: tendermint/tendermint#5459
