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.
