Angular’s NG8002: Invalid Attribute means the compiler cannot resolve a property or attribute binding on a template element. Check the binding’s spelling and syntax, then confirm that it targets a native DOM property or an input on an Angular component or directive applied to that element. If you mean an HTML attribute with no corresponding DOM property, use Angular’s attr. binding syntax.
What NG8002 means
Angular raises NG8002 when it cannot resolve a template binding during compilation. The binding name must identify either a native property on the HTML element or an input exposed by an Angular component or directive on that element. See Angular’s NG8002 error guide.
The error message identifies the element and unresolved name. Use those details to locate the exact binding in the template; the right correction depends on what that name is intended to target.

How to diagnose and fix NG8002
- Read the full error. Note the element and the binding name Angular cannot resolve.
- Check spelling and binding syntax. Compare the name with the actual DOM property or declared Angular input. A misspelling or use of the wrong binding form can trigger the error.
- For a native element, verify the target is a DOM property. Angular’s square-bracket syntax binds dynamic values to properties. For example,
<button [disabled]="isDisabled">Save</button>binds to the button’sdisabledproperty. - For a component or directive, verify its input. Confirm that the intended component or directive is applied to the element, exposes an input with the binding name you used, and is available through the declarations or imports appropriate to your project setup. Angular’s binding guide shows property binding on component and directive instances as well as native elements.
- For an HTML attribute without a matching DOM property, use
attr.. Angular documents syntax such as[attr.role]="roleName". When an attribute binding’s value isnull, Angular removes that attribute.
Choose the binding form for the target
| What you intend to set | Binding form | Example |
|---|---|---|
| A native DOM property | Square-bracket property binding | [disabled]="isDisabled" |
| An Angular component or directive input | Square-bracket binding using the exposed input name | [value]="currentValue" |
| An HTML attribute with no corresponding DOM property | Square brackets with the attr. prefix |
[attr.role]="roleName" |
These forms are not interchangeable: property binding targets a DOM or Angular property, while attr. sets an HTML attribute. Angular’s binding guide includes attribute examples, including cases such as some SVG attributes where an attribute binding is needed.

Check the component or directive input and imports
If the unresolved name belongs to an Angular component or directive, inspect its input declaration and the template’s use of that component or directive. A missing input, incorrect input name, or unavailable component or directive can leave Angular unable to resolve the binding. The official NG8002 guidance also lists an incorrect import and a missing direction with a property selector such as name among possible clues. Treat those as prompts to inspect the actual template and project setup, not as a universal correction.
NG8002 versus NG8001
NG8002 is about a binding on an element Angular recognizes; NG8001 is about an element Angular cannot resolve. If the error is actually naming an unknown element or selector, check the element name, the component or directive selector, and the relevant imports or exports using Angular’s NG8001 guide. Fixing a property binding will not resolve an unknown-element problem.

Adding NO_ERRORS_SCHEMA may make an unresolved binding stop producing a validation error, but Angular’s API documentation says its use is generally discouraged because it can hide real template errors. Prefer fixing the spelling, binding form, input, or project availability that caused NG8002. See Angular’s NO_ERRORS_SCHEMA API documentation.
CUSTOM_ELEMENTS_SCHEMA applies to custom elements; it is not a general fix for an ordinary misspelled binding or a missing Angular input. For a custom element, check the Angular guidance for that setup rather than assuming a schema change addresses the underlying issue.
