serverless-next.js: Error: Cannot find module 'next/dist/next-server/server/node-polyfill-fetch'

While deploying a Next.js app to AWS using Serverless, I get a 503 error. When I drill down into the logs, I find the error I’m recieving is Error: Cannot find module 'next/dist/next-server/server/node-polyfill-fetch'.

I’ve tried uninstalling and reinstalling. I was using the latest version of Next. I tried to downgrade to 9.3.4. I’ve tried to downgrade Serverless Next.js. I’ve tried downgrading Node from 12 to 10 in Cloudfront. Any help would be greatly appreciated.

Please let me know if there is any other information needed to help with this issue.

“serverless-next.js”: “^1.13.0” “next”: “^9.3.4”
