Build failed because of webpack errors (Next.js + AWS Amplify)

Hi,

I’m working on a Next.js + AWS Amplify project, but I can’t get it deployed :frowning: I did quite a few researches online but I haven’t found a solution to my problem.

This is the whole build log:

i don’t understand if I’m doing something wrong with Amplify (I have followed their guide and I don’t see anything wrong in my code), or if it’s something else.

Any ideas/suggestions/support would be really appreciated :cry:

Cheers,
Dave

Either this module doesn’t exist in your repo or the case of the filename is different than the one used in import statement.

Hi, I’m facing the same issue.

ModuleNotFoundError: Module not found: Error: Can't resolve './../components/ui/common/Faqs' in '/codebuild/output/src675342249/src/anh.pw/pages'

I do understand the error message but… i check the path (with the case of filename) and everything but can not find any thing wrong.

Please note that… local build is successfully and I use VSCode, double checked… still can not figure out why.

Do you have any idea to check?!

Thank you so much!

Solved!

Just read a comment from this next.js - nextJS build fails on Vercel because of Webpack errors - Stack Overflow

Solution:

it seems that even though my local components are Capitalized the remote branch had some components lowercased.
