n.search is not a function in custom provider

[KaungHtet-Naing]

I don't know why it always shows this error in my custom provider if anyone has an idea what I'm facing pls give me a hand. 🙏 Unhandled Runtime Error TypeError: n.search is not a function

class MyProvider extends OpenStreetMapProvider {
    endpoint({ query }) {
        return this.getUrl(
            `https://developers.onemap.sg/commonapi/search?searchVal=${query}&returnGeom=Y&getAddrDetails=Y&pageNum=1`
        );
    }
    parse(response) {
        console.log(response);
        return response;
    }
}
