Solutions

1. Verify the element selector in the tour step matches an element present in the DOM.
2. Remove or update steps that reference elements not rendered on the current page.

When it happens

Trigger: Triggered when introJs is started with a target element selector that matches no element in the DOM, typically because the element is not yet rendered or the selector is wrong.

Common situations: See trigger scenarios.
