Why is vercel showing a white screen?-CodePudding

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.

CodePudding user response：

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"))
