Get an error when trying to import the exported variable in another file nodejs file

unexpected token export
nodejs import
module.exports function with parameters
javascript require
javascript import function from another file
nodejs import function from another file
module.exports and import
export default

I have a file called TemplateGenerator and I have:

export const test= {
    "type": "bundle"
}
export const bundle= {
    "type": "bundle",
    "id": "bundle--bb7142cc-83d5-4feb-98c7-53997d25c368",
    "objects": [generateObservedDataObj(),generateObservedDataObj(),generateObservedDataObj()]
}

So when I try to import it in another js file called Results like this:

import {bundle} from '../utils/TemplateGenerator';

I get

 SyntaxError: The requested module 'file:///app/src/results/Results.js' does not provide an export named 'default'
     at Object.<anonymous> (/app/src/routers/Routes.js:1)
    at Generator.next (<anonymous>)
     at Object.Module._extensions..js (internal/modules/cjs/loader.js:699:10)
     at Object.<anonymous> (/app/src/server.js:1)
     at Generator.next (<anonymous>)

Am I missing anything?

It should be:

export default const ...

since it is the only function/variable exported.
