Bug report

Describe the bug

In the case using target: 'serverless' flag in next.config.js, the with-ant-design-less sample code build failed.

To Reproduce

1. Go to 'https://github.com/bokuo-okubo/next-with-ant-design-less-failed'
2. yarn
3. next => working fine
4. next build => Error

(also in the case remove target: 'serverless' flag, build works fine.)

Expected behavior

I tried to build with the check condition also options.dev flag, it works fine.

https://github.com/bokuo-okubo/next-with-ant-design-less-failed/blob/4ceee6c40d3a3e52ef52407715b3a056c03f9605/next.config.js#L34

In the case of using target: 'serverless' mode, config.externals contain the amp-toolbox-optimizer, so the something wrong around there.

Screenshots

• dump the option in the build time

yep, encountering the same problem

[skenan]

same problem here

[enochN]

Tried working on this as my first issue.
So it seems the issue has to do with some dependencies of antd (css-animation, rc-animate, rc-select and rc-table) which make use of the library component-classes@^1.26. This library seems to try to import a dependency indexof which is not declared as a dependency in it's package.json.

Adding "indexof": "0.0.1" to the dependencies of the "with-ant-design" and "with-ant-design-less" example projects helps resolve the issue.

Would that suffice as a solution to this problem?

[skenan]

@enochN did you test on https://github.com/bokuo-okubo/next-with-ant-design-less-failed? I still get the problem：TypeError: (0 , _styleChecker.default) is not a function

[enochN]

So when I go through the step to reproduce, I got two unrelated errors.
First was a failure to resolve react-ssr-prepass. After adding that, there was one error about a failure to resolve styled-components and then the main error in question, failure to resolve indexof.

Since the errors involving react-ssr-prepass and styled-components do not occur in the with-ant-design-less repo, I think it's fair to just add those packages to resolve them and isolate the problem at hand.

Now when I apply my proposed solution of adding the indexof package to the bokuo-okubo's repo, the solution works. You can find my efforts here.

@skenan I got the same problem when using ant design with nextjs. I run npm run build locally and it works fine, but when it comes to deployment, the error:

occurs to me. Have you found a way to fix this?

[aaazureee]

Update, found out that when I use Typography component, such as Typography.Text (from ant design), this error occurs. I'm not quite sure how to resolve this, which means not being able to use this component entirely.

[enochN]

@aaazureee Could you try adding "indexof": "0.0.1" to your dependencies? Doing that worked for the sample projects I tested with.

[thongdong7]

@enochN I cloned your project and run the build command, the issue TypeError: (0 , _styleChecker.default) is not a function still happen.

The value _styleChecker is {default: {}}.

[enochN]

Oh okay. I must be doing something wrong in my environment then. Will investigate further. Thanks

[aaazureee]

The weird thing is that my npm run build locally is working fine, but when deployed to zeit, the build log shows the error above.

[aaazureee]

Update: I fixed this by using next@canary instead, no more error during deployment build log.

[ZhengYuTay]

Have the same issue with the repo provided. Not entirely sure why Typography from ant design is breaking the build. Removing it will resolve the issue but it's not ideal
