HTL Syntax Error


Level 4

Actually, I am trying to use the below syntax

<span data-sly-use.params="${'tagname.js' @value=item.productFilterTag}" class="package-uses"

But getting this error

"Cannot get DefaultSlingScript: Identifier tagname.js cannot be correctly instantiated by the Use API"


And the tagname.js code is given below

use(function () {
    // you can reference the parameters via the this keyword.
    var resourceResolver = resource.getResourceResolver();
    var tagManager = resourceResolver.adaptTo(;
    var tag = tagManager.resolve(this.value);
    var name =;
    var title = tag.title;
	var pageLocale = currentPage.getLanguage();
    var localizedTitle = tag.getTitle(pageLocale);

    return {
        title: title,
