truffle exec scripts/seed-exchange.js --network kovan

Question

I've been running into an error when I attempt to seed my exchange/contracts on the kovan test network. Any help would be appreciated.

Using network 'kovan'.

I had the same issue and found that by using console.log(accounts) in seed-exhcange.js only one account was making it to this point.

So I checked truffle-config.js with some console.log() throughout.

I found that I had put a space after the comma between my PRIVATE_KEYS in the .env file.

After removing that space everything worked great.
