TypeScript complains when trying the provided typescript example

[katerlouis]

Type 'Events' does not satisfy the constraint 'Record<EventType, unknown>'.
Index signature for type 'string' is missing in type 'Events'.ts(2344)

I have "strict": true in my tsconfig.json; I don't know what else I might be doing wrong

[xiaweiss]

use type instead of interface

type Events = {
  foo: string
  bar: number
}
