getting "FindAll is not a function" error

Thank you for your investigation! I really missed the part about Object Browser requirement. Unfortunately, the solution you are suggesting is not what I can use. The above sample is just a simplified example, not the real-world problem.

If you check my original code in the first post, I need to get the list of mat-chip-row tags, which are located on the same level as the inputElement (alias item). And because watch list shows directly what I want under the node parentElement property (of the obtained alias element), I hoped to use it in my code. 

Is there another way to get the list of items according of my needs? Using alias element, pointing to the input, instead of direct parent element, is apparently not an option?     

In other words, is there a way to get a direct HTML parent (not mapped parent) of an element, which is referenced by the Alias object?   

Not sure if this is helpful, but here's a few coding examples that highlights the button. Example 4 highlights and deletes. Name mappings are not used

function examples()
{
    // Using Chrome, navigate to https://material.angular.dev/components/chips/examples
    var page = Sys.Browser("chrome").Page("https://material.angular.dev/components/chips/examples");
                
    var panel = page.FindElement("//example-viewer[@id='chips-reactive-form']//chips-reactive-form-example/section/mat-form-field//mat-chip-grid[@role='grid']");

    // Example 1
    var items = panel.FindAll(["CustomObjectType", "contentText"], ["MatChipRow", "regexp:(how-to.*)"], 100);
    for (var i = 0; i < items.length; i++) {
        Sys.HighlightObject(items[i]);
    }
    
    // Example 2
    var items = panel.FindAll(["CustomObjectType", "contentText"], ["MatChipRow", "tutorial*"], 100);
    for (var i = 0; i < items.length; i++) {
        Sys.HighlightObject(items[i]);
    }
    
    // Example 3
    var items = panel.FindElements("//span[@aria-describedby='mat-mdc-chip-7-aria-description']|//span[@aria-describedby='mat-mdc-chip-4-aria-description']");
    for (var i = 0; i < items.length; i++) {
        Sys.HighlightObject(items[i]);
    }

    // Example 4
    var panel = page.FindElement("//app-component-viewer[contains(., 'overview')]")
    // Fina all objects in the page, where CustomObjectType = MatChipRow
    var items = panel.FindAll("CustomObjectType", "MatChipRow", 100);
    // Iterate through all found objects, highlight them and then click the X button to close them
    for (var i = 0; i < items.length; i++) {
        Sys.HighlightObject(items[i]);
        items[i].Button(0).Click();        
    }
}

I also have this snippet of code,

function pagesize()
{
    var page = Sys.Browser("chrome").Page("*");
    page.contentDocument.Script.eval("document.body.style.transform='scale(0.8, 0.8)'");
    aqUtils.Delay(2000);
}

which performs JavaScript injections - which performs the same as if using Chrome DevTools. However, this functionality was last working in TC v15.55 and has been broken since.
