no valid href attribute value found on element '%s' in respo

Error message

no valid href attribute value found on element '%s' in response '%s'

What it means

ClickLink found a matching element, but its 'href' attribute is absent, so there is no URL to navigate to. The element matched the selector yet is not a usable link — e.g. an <a> used as a placeholder or a non-anchor element.

Solutions

1. Target an element that actually has an href attribute (a real hyperlink)
2. If the navigation is JavaScript-driven, issue the request directly with http.get() instead of ClickLink
