At build time only: Invalid token specified

[n1kalai]

in development mode, it works nicely, at vercel deployment it deploys but because of working on localhost has problems, but when i try to build and export it has error: "Invalid token specified"

at Object. (...\node_modules\jwt-decode\build\jwt-decode.cjs.js:1:1147)
at Module.1TCz (....next\server\pages_app.js:149:68) {
message: 'Invalid token specified'
}

can anybody tell what i do incorrect?

The token may be invalid or expired. Make sure you are using a valid token when deploying. The second reason could be "CORS". You should configure it with your deployed project URL like this:
app.use((req, res, next) => {
res.setHeader('Access-Control-Allow-Origin', 'https://linkerfolio.vercel.app');
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
res.setHeader('Access-Control-Allow-Headers', 'Content-Type, Authorization');
res.setHeader('Access-Control-Allow-Credentials', 'true');
next();
});
