next12 - Githubissues

I'd like to help with getting fab working with nextjs 12.

Here is my initial test procedure, which basically comes from the fab & nextjs docs:

$ npx create-next-app@latest fab-next12
$ cd fab-next12

Creating a new Next.js app in /Users/konsumer/Desktop/fab-next12.

Using npm.

Installing dependencies:
- react
- react-dom
- next

  run `npm fund` for details

- eslint-config-next

Initialized a git repository.

Success! Created fab-next12 at /Users/konsumer/Desktop/fab-next12
Inside that directory, you can run several commands:

  npm run dev
    Starts the development server.

  npm run build
    Builds the app for production.

  npm start
    Runs the built app in production mode.

We suggest that you begin by typing:

  cd fab-next12
  npm run dev

$ npx -y fab init                                                                               ✔

   [Initializer] Ready to proceed. This process will:
                   • Generate a fab.config.json5 file for your project

                   • Add .fab and fab.zip to your .gitignore
                   • Install @fab/cli and related dependencies using npm

   [Initializer] Ok, proceeding…

To address issues that do not require attention, run:
  npm audit fix

Some issues need review, and may require choosing
a different dependency.

Run `npm audit` for details.
   [Initializer] Done!
   [Initializer] Now run npm run build:fab to build your project and generate a FAB from it!

   [Initializer] 💎 All good 💎

I test with npm run dev first, to make sure nextjs works. npm run build:fab:

> npm run build && npm run fab:build

Not serverless build

You'll need to update your next.config.js file.

I add target: 'serverless' to next.config.js, run npm run build:fab again:
