In the document "2023_PxWeb Configuration.pdf" on page 111 and 112 is says that the body of the post should have an object called "LanguageSpecificSettings" that contains "Language", "CatalogTitle" and "CatalogDescription". But if you do a post with those parameters (and all other required params of course) you will get a 500 error with no describing error message.
This is because the documentation forgets to mention that LanguageSpecificSettings also required a property called "PublisherName".
