WASM Content Security Policy error

[goodwin74]

I use Vite+React+Nodejs. During tests (npm run dev) everything works fine.
But after building the frontend project (npm run build) an error is displayed in the browser console:

How can this be solved? Why does this problem arise?

Solution: express nodejs, add code before routing:

app.use((req, res, next) => {
    res.set({
        "Access-Control-Allow-Origin": "*",
        "Access-Control-Allow-Headers": "Origin, X-Requested-With, Content-Type, Accept",
        "Access-Control-Allow-Methods": "GET, POST, PATCH, DELETE, OPTIONS",
        "Content-Security-Policy": "default-src 'self'; script-src 'self' 'unsafe-eval'; connect-src 'self' https://cdn.jsdelivr.net https://unpkg.com",
        "X-Content-Security-Policy": "default-src 'self'; script-src 'self' 'unsafe-eval'; connect-src 'self' https://cdn.jsdelivr.net https://unpkg.com",
        "X-WebKit-CSP": "default-src 'self'; script-src 'self' 'unsafe-eval'; connect-src 'self' https://cdn.jsdelivr.net https://unpkg.com"
    });
    next();
});
