Research direction

Start with deploy/deploy_contracts.ts and hardhat.config.ts, then run the documented Ephemery setup and yarn deploy to reproduce the failure. Trace the deployment configuration around the reported hardhat-deploy error and verify that deployment completes without the TypeError.

Written by the indexing model from the issue text.

Description

I am trying to use the instructions here to deploy the protocol to the Ethereum Ephemery testnet.

Steps to reproduce:

  1. clone the protocol repo with:
git clone https://github.com/livepeer/protocol.git
  1. copy the .env.sample file to .env
  2. add a private key, corresponding to an address with funds on Ephemery, to PRIVATE_KEY=
  3. Add the following in hardhat.config.ts under networks:
        ethereumEphemeryDevnet: {
            url: `https://eth.ephemeral.zeus.fyi`,
            accounts: PRIVATE_KEY ? [`0x${PRIVATE_KEY}`] : undefined
        },
  1. Set the defaultNetwork in hardhat.config.ts to ethereumEphemeryDevnet.
  2. Run the following:
yarn
export LPT_DEPLOYMENT_EXPORT_PATH=~/Development/lpt_contracts.json
yarn deploy
  1. See error:
