Uncaught Error: unknown pubkey type: undefined

Hi,

So when running the following script using node I get the following output bellow:

const {
    Tendermint34Client
} = require("@cosmjs/tendermint-rpc");

async function main() {
        const client = await Tendermint34Client.connect('https://rpc.cosmos.network:443');
        await client.blockResults(9170003)
}

main()

The following is the output:

/home/krubot/Projects/test/node_modules/@cosmjs/tendermint-rpc/build/tendermint34/adaptor/responses.js:81
            throw new Error(`unknown pubkey type: ${data.type}`);
                  ^

Might be missing something obvious here but can’t workout why its saying the pubkey type is undefined. Should also be using the latest and greatest package here of @cosmjs/tendermint-rpc:

$ npm install @cosmjs/tendermint-rpc@v0.28.4

added 1 package, removed 2 packages, changed 8 packages, and audited 386 packages in 13s

  run `npm fund` for details

Thanks in advance any help here would be great!

Do you think this is a bug in the TM response or should the fix be made here to unwrap the Sum nesting? I can submit a PR for the latter.

I think for Tendermint 0.34 the format in the API will not change and we should adapt the client. If you can work on a PR that would be much appreciated.

Nice, thanks. Then let’s create a new type RpcPubkey2 or something like this.
