(accInfo.observer as Observer<BN>).error(err)

I am seeing this error when there is thrown an error "Connection not open" and
accInfo.observer is undefined.

addr is set to a DAO.

This is on rinkeby.

STEPS to force this error to happen:

1. clear any existing INFURA_ID environment variable in your shell
2. in the shell, run npm run start-staging
3. I'm really not sure: You may need to have an account already cached (so the "Connect" button will be showing)
4. using a fresh instance of your browser
5. run that build of Alchemy in your browser
6. navigate to Genesis Alpha (or probably any DAO)

RESULT:
You will see that the DAO token and ETH amounts say "N/A" and the quoted error message on the console.

Whether you can reproduce or not, I imagine this code can easily be made not to crash in this instance. Extra credit to clearly understand why accInfo.observer is undefined and whether there are any other ramifications in this use case.
