[Yan]

Reproduce:

1. Download the repo
2. Delete yarn.lock
3. run yarn
4. run the next app, i.e. yarn dev:next

I got the following error:

PS: The line info - automatically enabled Fast Refresh for 1 custom loader has come out twice...

What could be wrong here?

[pbassham]

Same here

[Raghav]

Add webpack5: true, in this config object https://github.com/axeldelafosse/expo-next-monorepo-example/blob/main/packages/next/next.config.js#L14. This seems to be an issue with @expo/next-adapter expo/expo-cli#4066

[Mark Lawlor]

Looks to be a regression in the webpack5 checking logic within Expo, with it now defaulting to webpack 4. The workaround is explicating setting webpack5: true in your next.config.js

See: expo/expo-cli#4066 (comment)

@rmylagary Yeah true. I have just noticed this issue...expo/expo-cli#4195 (comment)
