array-callback-return TypeError

[pat841]

What version of TypeScript are you using?
2.5.3

What version of typescript-eslint-parser are you using?
8.0.1

What code were you trying to parse?

export abstract class TestAbstract {

  onCreated?(): Promise<void> | any;

}

What did you expect to happen?
ESLint shouldnt fail when parsing the file.

What happened?
TypeError: Cannot read property 'type' of null
node_modules/eslint/lib/rules/array-callback-return.js:194:34

If I add a function body, it works:

  onCreated(): Promise<void> | any {

  }

Thanks @pat841, this is the same issue around TS function constructs not having a body interfering with expectations in ESLint rules. We are discussing the best way to address this right now
