Generate Username with Addy.io (AnonAddy) throws Error

### Production Build

- [ ] I'm using the legacy Bitwarden app pubicly available in App Store / Play Store and I'm aware that Bitwarden Beta bugs should be reported in [bitwarden/android](https://github.com/bitwarden/android) or [bitwarden/ios](https://github.com/bitwarden/ios)

### Steps To Reproduce

1. Open 'Generator' tab
2. Select _Username_
3. Under _Username Type_ select _Forwarded email Alias_
4. Under _Service_ select _addy.io_
5. Under _API access token_ use _API Token generated in addy.io portal_
6. Under _Domain name (required)_ use _custom domain name as in addy.io defined_
7. Click "regenerate" icon

### Expected Result

New Username generated and reflected in addy.io portal

### Actual Result

Error popup:
**builder error**

### Screenshots or Videos
