React.js Vercel Deploy Error Message | Error: No Output Directory named "build" found after the Build completed

I am encountering such an error while publishing the React.js typescript project I have made in Vercel. I haven't been able to find a solution.

Vercel publishing error as follows

// https://vitejs.dev/config/
export default defineConfig(async ({ mode }) => {
  return {
    plugins: [react()],

      alias: [{ find: "@", replacement: path.resolve(__dirname, "./src") }],

        define: {
          global: "globalThis",
        },
      },
    },

})

    }
  },

  "exclude": ["node_modules"],
  "references": [{ "path": "./tsconfig.node.json" }]
}

I'm waiting for the project to be published in vercel, but I constantly encountered this error. I even encountered similar errors on Heroku.

Solution

I had a similar problem. To fix this go to your Project setting => General and override the following commands:

Build command: yarn build

Output directory: dist

Development command: yarn dev

PS: Replace yarn with your package manager.
