AWS Codepipeline not serving React from a PHP+React Git repository

0

I am new to AWS and I was creating a Codepipeline for my GIT repository. My frontend is in React and backend is in PHP. So first I created an elastic beanstalk environment for php as backend. Then used AWS codebuild to build my code and finaly created a code pipeline.

Now issue is, when I am trying to access the pipeline I can only see php in it. React frontend isn't loading.

At first I thought maybe my react code is not getting build so I changed little react code and i got it's update in aws codebuild. So, I guess that's not the problem.

Please let me know if anyone needs any specific detail, I'll update my question.

This is my yaml file.
