dynamic sitemap for laravel seo

hi everyone, i'm a total newbie to laravel and just launched my first little app. I'm trying really hard to get the SEO side of things right, especially with a dynamic sitemap to make sure new content gets picked up by search engines quickly. it's been a bit of a struggle though.

the main issue i'm running into is getting the sitemap to auto-update reliably. it often feels like it's stuck on old content, or sometimes when i try to manually refresh it, i get this weird error. it's super frustrating because i want it to be future-proof and just work in the background.

[2023-10-27 14:35:01] local.ERROR: Failed to update sitemap: could not write to /public/sitemap.xml. Check file permissions. {"exception":"[object] (Illuminate\\Filesystem\\FileNotFoundException(code: 0): The file \"/public/sitemap.xml\" does not exist or is not writable. at /var/www/html/vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php:123)

so, what's the best approach to ensure a dynamic sitemap in Laravel auto-updates without me having to babysit it? are there any common packages or techniques for robust laravel seo sitemap management that you guys would recommend for someone like me? i'm open to anything that makes this process smoother and more reliable.

really appreciate any insights. waiting for an expert reply.
