Resolving Unrecognized Vue Variable in PhpStorm

I'm encountering an issue with my Vue script in PhpStorm. Despite setting the variable redirect_to, I am getting an Unresolved variable syntax error during debugging. Please refer to the image below for further information. How can I resolve this problem?

<script>
                const timeToRefetch = 2000;
                let intervalRef;

                const homePageUrl = "/";
                let messageCount = 0;


                var app = new Vue({
                    el: "#app",
                    data: {
                        status: "",
                        message: "",
                        redirect_to: ""
                    },
                    created() {
                        const refThis = this;
                        intervalRef = setInterval(() => {
                            fetch(ApiUrl)
                                .then(response => response.json())
                                .then(repos => {
                                        refThis.status = repos.status;
                                        this.message = repos.message;
                                        clearInterval(intervalRef);
                                        setTimeout(() => {
                                            window.location.href = repos.redirect_to;
                                        }, 3000);
                                    },
                                );
                        }, timeToRefetch);
                    }
                });
            </script>

When utilizing objects with keys that are only known at runtime (such as those generated or received through an ajax call) in your code, static code analysis cannot resolve them in the IDE. However, you can inform the IDE about the structure of your runtime data using JSDoc annotations:

/**
     * @typedef {Object} dynamicKeys
     * @property {string} status
     * @property {string} message
     * @property {string} redirect_to
     *
     */
...
 var app = new Vue({
        el: "#app",
        data: {
            status: "",
            message: "",
            redirect_to: ""
        },
        created() {
            const self = this;
            intervalRef = setInterval(() => {
                fetch(ApiUrl)
                    .then(response => response.json())
                    .then(
                        /**
                         * @param {dynamicKeys} data
                         */
                        (data) => {
                            self.status = data.status;
                            this.message = data.message;
                            clearInterval(intervalRef);
                            setTimeout(() => {
                                window.location.href = data.redirect_to;
                            }, 3000);
                        },
                    );
            }, timeToRefetch);
        }
    });
