How to solve Unknown custom element error in Vue?

The “Unknown custom element” error in Vue occurs when you try to use a component that hasn’t been properly registered or imported. Here are some steps to help you solve this error:

Register the component: If you’re using a custom component, make sure that it’s registered in your Vue instance or component. You can do this using the Vue.component() method, or by registering it locally in a component’s components option.

Import the component: If you’re using a component from another file, make sure that it’s imported properly. You can do this using the import statement, and then referencing the component by name in your template.

Check the component name: Ensure that the component name used in your template matches the name you registered or imported the component with. Component names are case-sensitive, so make sure that they match exactly.

Check the file path: If you’re using a component from another file, make sure that the file path is correct. Double-check the spelling of the file name and the directory structure.

Check the file extension: If you’re using a component from another file, make sure that the file extension is correct. Vue components should have a .vue extension.

Check the scope: If the component is defined in a parent component or outside the component’s scope, you may need to pass it down as a prop or inject it into the component.

By following these steps, you should be able to fix the “Unknown custom element” error and ensure that your Vue application is functioning properly.
