@name Invalid Attribute @category compiler @videoUrl https://www.youtube.com/embed/wfLkB3RsSJM @shortDescription Unknown attribute or input

@description An attribute or property cannot be resolved during compilation.

This error arises when attempting to bind to a property that does not exist. Any property binding must correspond to either:

• A native property on the HTML element, or
• An @Input() property of a component or directive applied to the element.

The runtime error for this is NG0304: '${tagName}' is not a known element: …’.

@debugging Look at documentation for the specific binding syntax used. This is usually a typo or incorrect import. There may also be a missing direction with property selector ‘name’ or missing input.
