I am developing a React-Django application and it runs locally. When I install it on a server running on cpanel, it just shows a blank page. My provider checked it and made the following statements:
- The python application is installed correctly on cpanel
- The cause of the error should be found on the developer side.
I made the simplest possible application: Simpletest Local mode: "Simple Test" text appears in the title and under the react logo
cpanel: Python application:
the text "Simple Test" appears only in the title and sends the following error message

Does anyone have any idea where I can look for the error?
The application can be cloned from this GitHub repository.
I would like to ask someone to try and install it on a server running cpanel. Does it have an application running?
Many thanks!
