How to redirect non-existent pages to error.php page in .htaccess file?

Question

Joomla

Hello. How to correctly set up a redirect of non-existent pages to the error.php page in the .htaccess file? Now, if you follow this link (for example) https://livion.ru/scsdcsd, a duplicate of this page is created, but you need to go to https://livion.ru/error. With such a link - https://livion.ru/1 goes to https://livion.ru/error. What to do?)
Thank you!

Answer 1

A 404 error should not redirect to another address, just a specific page should be displayed.
For example, https://livion.ru/1if there is no such URL, then the error page should open at this address, but not a redirect to https://livion.ru/error.
