Project Setup & Debugging
How to debug deployment issues?
Vercel CLI can be used to check builds from your local computer or development environment.
The vercel dev command is useful for running a development build, and vercel build can be used to make sure a build will succeed.
If a deployment is running into errors because of a missing environment variable, you can review the values you set in Project Settings or use the CLI to pull variables into a local file and check that they match what you expect.
You can also deploy projects from Vercel CLI if you want to create a new deployment without pushing test code to GitHub.
There are also guides available with examples of things you can do using Vercel CLI. For example, custom CI/CD workflows are a popular use.
Documentation for the CLI can be found at vercel.com/docs/cli
How do I add my own domain?
You can use an existing domain or buy a domain with Vercel. Step-by-step instructions are available in the docs at vercel.com/docs/getting-started-with-vercel/domains
How to I fix a problem with my domain?
We have advice for debugging many common domain issues in the domain troubleshooting guide at vercel.com/docs/projects/domains/troubleshooting
Why does my deployment have a 404 error?
A 404 means the requested resource could not be found. Here are some things you can check to determine the cause:
- Check the deployment URL for typos or incorrect paths.
- Make sure the deployment exists and has not been deleted.
- If the deployment exists, review the deployment logs for issues that might have caused the deployment to be unavailable.
- From the deployment details page > Source tab, toggle to Output, and verify that an index is available. This is sometimes missing.
- This can happen with some Express.js setups, for example, and the Express on Vercel guide helps in those cases.
- Projects not using a framework sometimes run into this as well. In that case, just make sure your site has an
index.htmlfile at the root of the project for the homepage.
- Check the Runtime Logs for errors preventing pages from being available.
- If you’re on a team with multiple people, make sure you have permissions to access the deployment.
