isExisting() returns Error if DOM is not present

[BavithiraG]

Describe the bug
isExisting() is expected to return false if the DOM is not present. Instead it returns below error
ERR: - Error: No DOM element found using the control selector

To Reproduce
invoke .isExisting() on any element not present

Expected behavior
isExisting() should return false

Logs/Console Output
[browser wdi5] ERR: - Error: No DOM element found using the control selector {"

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()

I tried your suggestion but I get error in wdi5 log although my test is passed. It is confusing. I would expect that error would go away.

async deleteAssessmentDisplayed(isDisplayed: boolean) { const deleteButtonExists = await (await browser.asControl(await this.getDeleteButtonSelector())).isInitialized(); await expect(deleteButtonExists).toBe(isDisplayed); }

This works better for me:

async deleteAssessmentDisplayed(isDisplayed: boolean) { const deleteButtonExists = (await browser.allControls(await this.getDeleteButtonSelector())).length; await expect(Boolean(deleteButtonExists)).toBe(isDisplayed); }
