Internal server error: Unexpected token 'export'

My name is Mustak!
As of right now, I am learning about the Shopify framework(Hydrogen) and am experiencing an error. Please help me to fix this.
It happened in the hydrogen default app.

Since it is my first time asking a question in the Shopify community, if I made any mistakes, please let me know what to do to get my answer.

This type of error can happen when the JS build system isn’t configured to support Ecmascript modules. It might be a better idea to raise an issue on the Hydrogen github repo, if this happens using the default template!
