Codesandbox-client: Manifest Error when Exporting default CRA template

[karlhorky]

🐛 bug report

Description of the problem

Because there is no manifest.json file in the default create-react-app template (related to #1532), exporting and running yarn start gives the Manifest: Line: 1, column: 1, Unexpected token. error because HTML is getting served instead of JSON.

How has this issue affected you? What are you trying to accomplish?

Export + yarn start default CRA template without browser console errors.

Simple explanation here is that our create-react-app template is not a 1;1 clone of the official create react app starter files, so that would be the source of this bug.

We're looking to address this in an upcoming overhaul of templates on the platform. Thanks for reporting this and we'll address it as soon as possible!

For now all I can offer as a solution is to add the missing files that create react app expects yourself when attempting to run the code on your local machine. We can't retroactively add missing files to Sandboxes forked from the existing React template without running the risk of overwriting a user's changes.
