[Bug]: Validator signing infos with empty addresses

[livthomas]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

When fetching validator signing infos either via RPC or REST API, some records contain an empty address. Because of this issue, it is not possible to map these records to specific validators. It is probably a serialization problem with some addresses because returned records contain other data such as missed blocks counter.

{
  "info": [
    {
      "address": "",
      "start_height": "0",
      "index_offset": "20124324",
      "jailed_until": "1970-01-01T00:00:00Z",
      "tombstoned": false,
      "missed_blocks_counter": "0"
    },
    {
      "address": "",
      "start_height": "0",
      "index_offset": "20409039",
      "jailed_until": "1970-01-01T00:00:00Z",
      "tombstoned": false,
      "missed_blocks_counter": "16"
    },
    {
      "address": "",
      "start_height": "0",
      "index_offset": "558390",
      "jailed_until": "1970-01-01T00:00:00Z",
      "tombstoned": false,
      "missed_blocks_counter": "0"
    },
    {
      "address": "",
      "start_height": "0",
      "index_offset": "692329",
      "jailed_until": "1970-01-01T00:00:00Z",
      "tombstoned": false,
      "missed_blocks_counter": "0"
    },
    {
      "address": "cosmosvalcons1qzgr0sk82ce080u78xs3cr5pat9jvtv7k85ajv",
      "start_height": "10199254",
      "index_offset": "6811705",
      "jailed_until": "1970-01-01T00:00:00Z",
      "tombstoned": false,

    },

Cosmos SDK Version

v0.45.16

How to reproduce?

1. Go to https://v1.cosmos.network/rpc/v0.45.1
2. Set rest.cosmos.directory/cosmoshub as the Base URL
3. Try to call GET /cosmos/slashing/v1beta1/signing_infos
4. See records with empty addresses in the response

Alternatively, you can reproduce it by running a simple script that I created when I reported the same issue in cosmos/cosmjs#1436.

Hi,

v0.45.x is not supported. The Cosmos Hub uses a deprecated version.
Can you reproduce in v0.46.x+? If not, we will need to close this as won't fix.
I have quickly checked a few chains (e.g https://juno-rest.publicnode.com/cosmos/slashing/v1beta1/signing_infos / https://kava-rest.publicnode.com/cosmos/slashing/v1beta1/signing_infos), without being able to see the same behavior.

I'm not able to reproduce it on any other chain either.

Alright, feel free to open an issue on https://github.com/cosmos/gaia then 👍🏾

@julienrbrt Thanks for the suggestion. I can see it has already been reported there. cosmos/gaia#1734
