💻 Code

export type State = { a: number; b: string; }; export class Test{ setState(state: State){} test = (e: any) => { for (const [key, value] of Object.entries(e)) { this.setState({ [key]: value, }); } }; }

🙁 Actual behavior

running tsc results in a crash:

TypeError: Cannot read properties of undefined (reading 'kind') 

🙂 Expected behavior

No crash is expected, some type errors should be found instead.
