[Vue warn]: Extraneous non-emits event listeners (mouseenter, mouseleave) were passed to component but could not be automatically inherited because component renders fragment or text root nodes. If the listener is intended to be a component custom event listener only, declare it using the “emits” option.

Runtime directive used on component with non-element root node. The directives will not function as intended.

[Vue warn]: A plugin must either be a function or an object with an “install” function.

Component “default” in record with path “/” is a function that does not return a Promise. If you were passing a functional component, make sure to add a “displayName” to the component. This will break in production if not fixed.
