I've developed NextJS Project and already deployed to Vercel. Today when I updated my code and pushed to Github, and begin to deploy on Vercel, it shows me error. Build logs is attached in screenshot.
I've tried to delete node_modules, cleaning cache and all, but it didn't work.
The strange thing I'm not seeing any error and the reason for failing. In my local host, everything is working perfectly and no errors whatsoever, but Vercel is not giving me any error but just one notification:
Error: Command "npm run build" exited with 1
Can somebody let me know please what could be the reason of it? I can see there are some warnings but these warnings I suppose are not the main cause of this strange issue.
Thanks for reply. After spending 2-3 hours , I had intentionally put an error in my code, deleted one dependency from node_modules to see the build logs of Vercel. And removed a component from my code. So during deployment on Vercel of ERROR Code, it has shown me the errors indeed. And when I undo my changes and again started to deploy, that works like a charm. Not sure what was the reason still. Might be Vercel got some bugs at that period of time in my account. LOL
Removed one of the dependency from package.json
Then Deployed again to Vercel. Then it has shown me some error that makes sense.
Screenshot is attached.
Errors shown in Vercel
After fixing that error, it worked !

This is my 5th project deployed to the Vercel via GitHub (after almost year break). However after importing the project from the GitHub and pushing it to Vercel I am getting 404 page with a link to unhelpful page with explanation why I might see the 404 page (which naturally does not resolve even remotely the issue). I don't understand. My previous 4 projects were deployed this way and they work to this day. Simple push to the GitHub will update the project and publish it live. The projects says it is build, there are no errors. It works on local building it with npm run dev.
The project was added the recommended way as per the Next documentation using npx - command was copy-pasted from the documentation.
I have consulted this with how to publish Next.js project to Vercel and there are simple 4 steps which I did.
Does anyone maybe had similar experience and managed to resolve this kind of issue? Thank you kindly for your time.
I am running Gatsby + WP and have not seen this error until updating my gatsby-source-wordpress plugin.
The error message does not give me any information about where this is occuring so I am compeltely stuck.
I tried simply clearing my cache but that didn't do anything.
I am not getting errors in my local environment, but I when I push this to Gatsby cloud the build fails and gives me the message.
I am not sure if my answer will be helpful to you. But I had the same error when I pushed my code which worked fine in my local environment.
After spending some time debugging, I realised that the problem that stopped building wasn't related to the error message at all.
After I fixed the bug I still got the same error but the build succeed. So I recommend you try to check another factor that might cause the build to fail.
Background:
We are have noticed that in production and in some staging environments, that the onClick handlers on a SSR page are failing to be called. By comparing working and non-working (npm run start) deployments we've determined that the non-working deployments are not calling the render() methods of the components on the page immediately after page reload, whereas the working deployments do. We are assuming that means that hydration is not occurring.
Development deployments (npm run dev) work flawlessly
We are seeing no browser-side console messages.
We are seeing no server side warnings
The npm build --debug suggests only to upgrade to the new ChunkGraph API. Otherwise no warnings.
We are now wondering...
QQ:
Short of starting with a fresh create-next-app again and gradually evolving the app towards our current implementation until it breaks, what are the suggested ways of determining the root cause(s) of a problem like this?
For some reason, my hydration issues only showed up in production, and only on the server. Running next build and next start didn't show any errors. Since user3624334's answer didn't really help me, I figured I'd reply with how I ended up finding the culprit.
Since I deploy to Vercel, and use Vercel's review apps, I ended up creating a Pull Request where I remove half of the page that was having the hydration issues, and continued bisecting until I found out which component was causing the issues. It took me three tries to find the component.
Once I had the component it was quite easy to figure out what was causing the issues (for me the hydration issue was caused by a timestamp being rendered in different ways).
This also explains why user3624334's answer didn't work for me, since I opened the page straight after building, at which point the time was still the same as during next build!
One challenge here is that it appears that when SSR page hydration fails in next.js, a warning message will not necessarily be generated.
I hope someone has a better suggestion than the following, but I will offer this human script that worked several times for me:
git checkout -b "hydration-problem-02" to create a branch for this effort
add a console.log('render called') to the top of the render() method of pages/_app.js. This should produce a message on each hydrate, making it easy to notice when the page does/does-not hydrate.
Then repeatedly:
simplify a significant portion of the app.
npm run dev to run in dev mode
confirm that your change did not break the app in unexpected ways
rm .next/ node_modules/ package-lock.json
npm install && npm run build && npm run start
confirm that the above command completed successfully
refresh the page in the browser
check for the message in the browser console.
git commit -am "msg that indicates what you changed and if it helped"
if the problem remains, repeat these steps
Doing the commits above should help make the process more fool-proof. Ex. If you think you might have forgotten to test in production mode, you can go back to that commit and retest to confirm you did not mis-test.
Once you have a working and non-working commit of the app, you can do a binary search for the error, either adding or removing smaller and smaller pieces of function.
The root causes of quiet hydration failures I've seen include:
two modules that mutually import each other
an import '..../bootstrap.js' in a component rather than _app.js
i also meet this problem when meteor run iOS,the error like this,can you give me some advice?
the error is in the attached picture.
You could try first to delete the .meteor/local/cordova-build/ folder.
Meteor will re-build it entirely when you launch the meteor run ios command.
This troubleshooting step resolves such issues most of the time.
I'm trying to use the Artifactory-Plugin for bamboo to deploy a tar.gz into artifactory. However, after the build went successful, the plugin won't even try to deploy and instead just writes
Build failed, not deploying to Artifactory.
I have no idea, why it would think, that the build failed. Does anyone else know this problem and has a suggestion on how to solve it?
As I just noticed, there was actually an error in my build before, which I didn't see, because it wasn't critical and was well hidden in the hundreds of lines of log. After getting rid of that error, it worked.
BAP-195 Was filed for this issue.
In my case Artifactory plugin fails to deploy even if build scripts has failonerror="false".
