Current build behavior works for frontend which looks like: 2024-12-03@00.33.04 December-03@2x

Current build behavior does not work for backend which looks like: 2024-12-03@00.22.05 December-03@2x

Back-end: Strapi v5

Hi , thanks for posting this question on the community.

The context you provided will come very handy. Did you already check the build and deployment logs for these projects? Could you share the error messages from the logs (if they don't include sensitive information)?

Hi , thanks for the reply.

The build logs look fine.

By default, the logs are set for Past 30 minutes (see left pane). So, if you make new requests and then check the logs, we might find error logs to debug.Could you try visiting the page again and then check the logs?

Also, check the logs for both the frontend and backend project.

reply to #4

Video shown and then removed (Video shows no logs upon refresh of deployed site, deployed site which shows the same error referenced in this post's description).

Vercel Staff

Hey, I saw the video. Thanks for sharing it. You can edit the comment to remove the link now.

Let me dig a bit more to see how we can debug it.

Vercel Staff

Hi , from the build logs I see that the output of the build seems to be /build folder. Can you update the project settings to use the /build folder as the Output Directory?

I'd also recommend comparing your project configurations with the https://github.com/strapi/nextjs-corporate-starter/blob/main/backend/README.md example we have.

GitHub

nextjs-corporate-starter/backend/README.md at main · strapi/nextjs-corporate-starter

Strapi Demo application for Corporate Websites using Next.js - strapi/nextjs-corporate-starter

Changing the output directory to build and /build then redeploying from main did not fix the issue sadly : (

reply to #8

Where do you see the output of the build being the /build folder?

Below is a screenshot showing the build step, and the only output path I see referenced is /vercel/output.

2024-12-03@15.44.07 December-03@2x

I tried setting the output directory as /vercel/output and vercel/output and neither worked as well.

I noticed that there's a vercel-deploy plugin but it's only compatible with strapi v4. https://market.strapi.io/plugins/strapi-plugin-vercel-deploy I wonder if it's just not possible to deploy Strapi v4.9+ projects to Vercel without custom extensions for it? The link you sent me is for strapi 4.2. I'm running a Strapi v5 project.

reply to #9

Vercel Staff

Hi , thanks for sharing the outcome. My guess was that some frameworks output the build to /build instead of /dist. You can see that for your project in the Deployment section, see this image:

Deployment summary for build outputs

The /vercel/output is an internal space for the Vercel platform and shouldn't be used or referred to elsewhere.

Let me try and recreate this issue with you.

I appreciate the info and you trying to reproduce the issue! Just let me know if there's any other info you need.

Vercel Staff

Hi , I did some digging around and found out that the output for the Strapi CMS itself is supposed to be hosted on a server instance (EC2 or similar) instead of a serverless platform like Vercel.

You can read more about Strapi CMS deployment on their documentation.

However, you can deploy the frontend application on Vercel. I tried running their latest LaunchPad project and it uses Next.js for the frontend website, so you can definitely follow this repository to deploy the frontend. But, the /strapi part of this also builds into a server application because of all the system requirements such as a database and OS utilities.

I hope this was helpful.
