this is a little hard to grasp as there's no minimal reproducible sample provided, not even sample code.
yet I'm guesstimaiting you're referring to the wdio (not wdi5!) element method .isExisiting() → https://webdriver.io/docs/api/element/isExisting
wdi5 sits on top wdio. So if you're doing something along the line
await exists = browser.asControl(selector).$().isExisting(); expect(exists).toBe(false)
this will fail b/c browser.asControl() can't retrieve the DOM element (as it doesn't exist, meh) and subsequent operations on that are not possible.
Instead, please use
await exists = await browser.asControl(selector).isInitialized(); expect exists.toBeFalsy()
