Parsing error: Cannot read property 'map' of undefined

See original GitHub issue

Current Behavior

export type Tuple = [number, number];

after running yarn lint getting error 0:0 error Parsing error: Cannot read property 'map' of undefined. Build and test commands work fine.

Additional context

Tried the same in Create React App, seems to be working fine.
