Sitemap not displaying if site in subdirectory

I am encountering the same issue on Version 4.1.9. In my local DDEV environment, everything works perfectly without any issues.

However, on the production server hosted on AWS, a blank page is displayed on /sitemap.xml. If I uncheck the option Add styling and sorting to sitemaps in the module settings, then the XML file is displayed.

Could someone please look into this?

Updated the patch mentioned here 🐛 Sitemap not displaying if site in subdirectory Fixed to make it compatible with version 4.2.2

Bug reports can only be opened against the dev version of the module - Can't change an existing release.

I just had a brief look at your patch; what happens when base URL is not set in the module settings?

Can anyone else confirm this to still be an issue?

#18 worked for me.
Disabling the styling option fixed my issue.

I just ran into this issue from the CLI.

If I rebuild the queue and generate the sitemap from /admin/config/search/simplesitemap, it worked out of the box... but I was trying to get the experimental Config Actions API working with a recipe to install the modules, set up the sitemap configs, AND generate the desired sitemap with those settings in one shot.

I got a recipe to mostly work using php core/scripts/drupal recipe ../recipes/simple_sitemap, but the base URL wasn't being set properly so I was getting a sitemap with "http://:core/scripts" in the XSL file (and included image) URLs (with "no XSL stylesheet" found error).

Setting simple_sitemap.setting.yml -> base_url config fixes the image URLs, but the xml-stylesheet href tag still had the bad base_URL.

And this patch → was causing the problem. I removed that base_url() and added a '/' in front of $xsl_url in the writePI(), and the XSL stylesheet started working from the CLI.

(There's probably a way to locally get a correct base_url value when running the drupal script (CLI), but it should be dealt with at the module level.)
