Serverless-webpack dependency error: @babel/runtime.
This is a (Bug Report)
Description
I'm upgrading my Next.js app which runs on AWS Lambda using serverless-offline and serverless-webpack plugins. The upgrade from Next 5 to Next 8 forces me to upgrade my babel/webpack dependencies, but it's very hard to get it right.
Currently, my frontend app (:3001) works alright (just next alone), but my serverless-offline app fails to start due to transpilation issues (AFAICT).
Here are the logs when I try to run serverless package

Current behavior: Compilation fails at runtime
Here are my scripts for starting my app locally:
"start": "yarn sls:dotenv && cross-env-shell 'concurrently -p '{name}' -n 'client,server' -c 'gray.bgWhite,yellow.bgBlue' \"yarn start:client\" \"yarn start:server\"'",
"start:client": "NODE_ENV=development GROUP_NAME=${GROUP_NAME:-demo}; GROUP_NAME=$GROUP_NAME next -p 3001",
"start:server": "NODE_ENV=development GROUP_NAME=${GROUP_NAME:-demo}; GROUP_NAME=$GROUP_NAME serverless offline start --dontPrintOutput",
The clients runs successfully, but the server crashes.
When I start my app using yarn start, here are the logs:

Hi @Vadorequest, thanks for the report 👍
It seems, that you need a missing babel transform in your babel.rc to get rid of "SyntaxError: Unexpected token import"
Additionally, @babel/runtime might be needed as dependency.
Could you try that?
Thanks for the feedback @HyperBrain , I don't really understand what I should change in my .babelrc though. (is it a missing plugin?)
As for @babel/runtime, I moved it from devDepencencies to dependencies in package.json, thanks for the hint!
I've removed a few things from package.json as specified in https://github.com/zeit/next.js#customizing-babel-config
- @babel/plugin-transform-runtime (also removed from .babelrc)
- @babel/preset-env
- @babel/preset-react
But still the same error.
