[Question] What about "Property X does not exist on type 'object'"?

## Description

I'm facing the following error:

```
Property 'onError' does not exist on type 'object'.(2339)
```

## Reproduction

```ts
export interface Reporter {
onError: () => void
}

export type AnyFunction = (...args: unknown[]) => unknown

export function isObjectLike(value: unknown): value is object {
return value !== null && typeof value === 'object'
}

export function isFunction(value: unknown): value is AnyFunction {
return typeof value === 'function'
}

function isReporter(value: unknown): value is Reporter {
return (
isObjectLike(value) && 'onError' in value && isFunction(value.onError)
)
}
```
