Expected Behavior

I expect default import in index.js (actions) to be present

Current Behavior

Default import in index.js is not present. I am getting an error instead:

"export 'default' (imported as 'actions') was not found in './actions'

This is somehow related to transform-runtime plugin along with using computed property names in default export. When I disable transform-runtime, everything works properly. My current workaround for this:

const actions = { ... }

export default actions;
