Cannot find module '../lib/load-env-config' after upgrading to 9.3.2

[olpeh]

Hey!
Due to this https://twitter.com/zeithq/status/1243265976361156608, I'm trying to upgrade to 9.3.2.

However, after upgrading, our app does not start, because of a missing dependency:

node_modules/next/types/index.d.ts:8:21 - error TS2307: Cannot find module '../lib/load-env-config'.

8 import { Env } from '../lib/load-env-config'
                      ~~~~~~~~~~~~~~~~~~~~~~~~

yarn why load-env-config
~~~~~~~~~~~~~~~

yarn why v1.21.1
[1/4] Why do we have the module "load-env-config"...?
[2/4] Initialising dependency graph...
[3/4] Finding dependency...
error We couldn't find a match!

Any clue about why this happens and how to resolve this?

Patched it this morning, doing a new canary release right now so that you can try it out 👍

Alright, thanks!

Now, we have a different issue when trying to upgrade to 9.3.3 @timneutkens 😅

Running locally works, but creating a build fails with the following error:

Actually this error is resolved by upgrading babel related dependencies.

Now there's another issue in the build, but that might be related to our custom setup.

[olpeh]

It fails in Automatically optimizing pages and specifically the /404, is there a way to disable this for that page?

[olpeh]

We were able to "fix" this by opting out of Automatic Static Optimization for our _app.tsx
