Cannot convert undefined or null to object

[flipchan]

Hey, I'm trying to get fork-off-substrate to work with https://github.com/edgeware-network/edgeware-node/tree/erup-5-latest.

I assume it's because I have not added the custom types but, I have imported them into the index.js file(const { spec } = require('@edgeware/node-types');) and that should work. Am I missing something here that causes problems?

HTTP_RPC_ENDPOINT=http://mynode:9988 npm start

> fork-off-substrate@1.0.0 start
> node index.js

We are intentionally using the HTTP endpoint. If you see any warnings about that, please ignore them.
