Web3Provider not working

I do `yarn serve` and visit http://127.0.0.1:8080/
I try sending a TL update request with metamask and receive the error message:

```Error: invalid address - undefined (argument="name", value=undefined, version=4.0.23)```

The only potentially useful info I have is: https://ethereum.stackexchange.com/questions/19524/invalid-address-error-when-interacting-with-a-smart-contract-with-metamask
