In OWL, portals are used to render components outside the main component hierarchy, often for modals, popups, or tooltips. This error suggests that the target DOM element for the portal is either missing or incorrectly specified.

     class Portal extends Component {

        setup() {

            const node = this.__owl__;

            onMounted(() => {

                const portal = node.bdom;

                if (!portal.target) {

                    const target = document.querySelector(this.props.target);

                    if (target) {

                        portal.content.moveBeforeDOMNode(target.firstChild, target);

                    }

                    else {

                        throw new OwlError("invalid portal target");

                    }

                }

            });

            onWillUnmount(() => {

                const portal = node.bdom;

                portal.remove();

            });

        }

    }

    Portal.template = "__portal__";

    Portal.props = {

        target: {

            type: String,

        },

        slots: true,

    };
