Stuck with this error as well, I have no idea how to fix it 😦. I am using TS with next and react-apollo.

On line 1 in the optimism.js in apollo-cache-inmemory node_modules folder I replaced this line var wrap = require('optimism').wrap; with import { wrap } from 'optimism/lib'.

And now my app has started working again.

I guess this is a workaround for now, and I’m still trying to investigate why this is happening.
