App doesn't run locally

Hi Team,

I am currently facing an issue where only our application’s frontend UI is not running properly in the local environment. At the same time, the sample application is working fine when run locally.

Because our app UI is not working locally:

* I am unable to properly test UI-related changes.

* Every small update requires deployment to the serverless environment.

* Verification is possible only after the Monday deployment.

* This significantly increases development and debugging time.

If our application could run successfully in the local environment like the sample app, it would be extremely helpful for:

* Faster testing

* Easier debugging

* Quicker UI changes and validation

* Reduced dependency on weekly deployments

I would really appreciate your help in identifying what is missing in our local setup and how we can align it with the sample app configuration so that our frontend UI also runs locally
