counter.js breaks with fatal error when connected by tendermind

[paceto256]

How to reproduce:

1. checkout and build tendermint (current commit 1f8bb74bba0523aacdb76ed140339c48078c669b)
2. checkout js-abci (current commit 7fbe69092c815b6b2040ff2b302c428c0bd38cf9)
3. start the counter.js example node example/counter.js
4. start tendermint

./build/tendermint start

Swith to the counte.js tab, It breaks with the error:

    return RangeError("index out of range: " + reader.pos + " + " + (writeLength || 1) + " > " + reader.len);
           ^

tendermint should be call with abci parameter:

tendermint start --abci grpc

@paceto256 , how did you manage to run the exmaple? I'm trying to start it from the same exact commit, and I'm getting:

➜  js-abci git:(master) ✗ node example/counter.js
internal/modules/cjs/loader.js:905
  throw err;
  ^

I've managed to run the example by changing the let createABCIServer = require('abci') to let createABCIServer = require('../src/server')

Starting the tendermint with tendermint start --abci grpc ends with

• no block are being produced.

If someone is looking for a working example of counter.js, then tendermint 0.32.12 worked for me - without introducing any changes, all the messages are correctly processed. Changing counter state via curl or by RpcClient working as well.

Hope it helps save some time for others.
