NG8002: 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 the error

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.
