NextJS - null is not an object (evaluating 'anchorElement.parentNode') - amazon-web-services

Question

I am working on AWS, it works for 1 years with no errors.
Today I made some updtes on my code (I didnt update any packages), and It begins to return this.
I am using AWS CodeBuild, and I guess It must be about that (It may be updated or sth.)
But couldnt resolve tthe problem.
Unhandled Runtime Error
TypeError: null is not an object (evaluating 'anchorElement.parentNode')
Call Stack
eval
[native code]
./src/assets/scss/style.scss

What could be wrong?
It works on vercel when I try to build,
But It returns error on AWS. (It was working for 1 year)
