Describe the Bug

npm run build fails with the following error:

Module parse failed: The keyword 'yield' is reserved (453:107)
File was processed with these loaders:
 * ./node_modules/next/dist/build/webpack/loaders/next-swc-loader.js
You may need an additional loader to handle the result of these loaders.

when looked closely at the code, there is an await call which is converted to as yield throwing an error.

Not sure why this is throwing as an error.

Expected Behavior

Build should pass.

To Reproduce

Write a function with async/await.

Run npm run build.

Can you try again? There was a publishing issue with npm

+1 Seeing the same issue. This code uses an await and is replaced by yield when compiled. Issue presented going from next.js 12.0.1 -> 12.0.4
