TYPO3 v12.4 500 Page Not Found - The page did not exist or was inaccessible. Reason: No TypoScript record found

Question

I'm learning the newest typo3 CMS. I installed it through docker, and in the php container I installed the typo3 cms with that code: composer create-project typo3/cms-base-distribution:^12 example-project-directory. I logged in in the backend like mywebsite.localhost/typo3. I created a new page, added some content like "regular text element", but when I open it in the browser, I get the 500 error "500 Page Not Found - The page did not exist or was inaccessible. Reason: No TypoScript record found!" What should I do to get rid of this error? Sadly there is no tutorial about the v12.4 verison, all the content is outdated on youtube, also I didn't find any straight answer in the documentation.

The following TypoScript setup code is enough to remove this warning:

# Default PAGE object:
page = PAGE
page.10  < styles.content.get
