Why is vercel showing a white screen?

I am trying to deploy my portfolio website. It shows the proper log-in animation but then just shows a white screen. I have no idea why this is happening, the logged error message references unhelpful code from the site generator.

Solution

  • the error is in console. and in Skills.js file in line 48.

    TypeError: Cannot read properties of undefined (reading 'map')

    you can fixed it by adding question mark like this :

     { skillsSection.skills?.map((skills, i)=> ....

    and there is another error : twitter.js:14 Uncaught TypeError: Cannot read properties of null (reading 'innerHTML') in twitter.js file in line 14

    just add question mark there too. like this :

    if (!document.getElementById("twitter")?.innerHTML.includes("iframe"))
