Error: Invalid string. Length must be a multiple of 4

[msedzins]

Summary of the bug

We try to use the newest CosmWasmJS (1.1.1) to connect to newest Wasmd (taken from main branch). Transaction gets committed successfully on chain but as a response we get this error in the client:

/Users/msedzinski/git/client/node_modules/base64-js/index.js:26 
[1]     throw new Error('Invalid string. Length must be a multiple of 4')

I think the error is related to those issues (already closed):
cosmos/cosmos-sdk#11997
ping-pub/faucet#4

Solution, mentioned there, is to update cosmjs client.

Are there any plans to do that anytime soon?

Versions

CosmWasmJS 1.1.1
Wasmd - main branch
CosmJS - 0.28 (which seems to be to old)

Steps to reproduce

1. Run Wasmd
2. Generate transaction from CosmWasmJS that emits event
3. Error happens each time
