Please can u fix this error and make a standard XML file generated.
Below is the error:
Your website does not have an XML sitemap - this can be problematic.
A sitemap lists URLs that are available for crawling and can include additional information like your site's latest updates, frequency of changes and importance of the URLs. This allows search engines to crawl the site more intelligently.
We recommend that you generate an XML sitemap for your website. It is also good practice to specify your sitemap's location in your robots.txt file.
It's important to only include pages that you want the search engines to crawl, so avoid any that have been blocked via your robots.txt file. Check the URLs to ensure that none of them cause redirects or return error codes. This includes being consistent with your URLs, for example, including your preferred URLs (with or without www.), including the correct protocol (http or https) and making sure URLs all end with or without a trailing slash.
