Hey everyone, I’m stuck with a weird issue in my Nextjs app. It’s a remake of an old Django project. Everything runs smoothly in dev mode but when I try to build it, things go south.
At first, I had to fix a bunch of type errors. Now the build starts but keeps timing out while generating static pages. It consistently stops at the 15th file, even after removing all API calls to my Django backend.
I’m also getting the error ‘Event handlers cannot be passed to Client Component props’ often, which happens when passing button functions meant for closing popups or updating content. I’ve tried adding ‘use client’ to the relevant files and making the components client-side, but nothing seems to work.
I’m new to Nextjs and feel like I’m overlooking something obvious. Any insights on what might be causing these build issues would be greatly appreciated. Thanks!
Having migrated several projects to Next.js, I can relate to your frustration. One often overlooked aspect is the difference in environment variables between development and production. Ensure your .env.local file is properly set up for the build process.
For the timeout issue, consider implementing dynamic imports for heavy components or data fetching. This can significantly reduce the build time and prevent timeouts.
The ‘Event handlers cannot be passed to Client Component props’ error typically occurs when you’re inadvertently mixing server and client-side code. Review your component structure and ensure clear separation between server and client components.
Lastly, run ‘next build --debug’ for more detailed error logs. This often reveals underlying issues not apparent in the standard build output. It’s a powerful tool for pinpointing exact problem areas in your codebase.
yo ethan, had similar probs. try this: clear ur .next folder n node_modules, then npm i again. sometimes cached stuff messes things up. for the event handler thing, make sure ur not passin functions from server to client components. wrap em in useCallback if needed. gl mate!
I’ve faced similar issues while migrating from Django to Next.js. The build failing while dev mode works is often due to differences in how Next.js handles server-side and client-side code during build time.
For the timeout issue, try increasing the build timeout in your next.config.js file. Add something like:
module.exports = {
staticPageGenerationTimeout: 1000,
}
This gives Next.js more time to generate static pages.
Regarding the ‘Event handlers cannot be passed to Client Component props’ error, ensure you’re not passing function references directly to client components from server components. Instead, pass data and handle events within the client component itself.
Lastly, double-check your import statements. Sometimes, circular dependencies or importing server-only modules in client components can cause build issues that don’t show up in dev mode.
Hope this helps you troubleshoot. Let me know if you need more specific advice!
