[4.0][Cassiopea] Wrong ItemId: Call to a member function getParams() on null

[bato3]

Steps to reproduce the issue

Go to article (without mod_rewrite) with wrong itemid
/index.php?option=com_content&view=article&id=187&Itemid=64

Expected result

HTTP 200 / 404

Actual result

HTTP 500
0 Call to a member function getParams() on null

System information (as much as possible)

Additional comments

From stack is line 29 in template/cassiopea/index.php

$pageclass = $menu->getParams()->get('pageclass_sfx');

My quick fix:

$pageclass = empty($menu)?'':$menu->getParams()->get('pageclass_sfx');

is not working completely correctly because the breadcrumbs are not working properly (shows the home page)

I can't reprodue that here on a clean, current 4.0-dev with blog sample data, SEF URLS=off, no URL rewriting. And I know at least one other contributor who can't reproduce.

Could you provide some more information about your configuration regarding SEO options in Global Configuration, and if you have an .htaccess file and so on.

How does it normally work for you when having a 404? Do you see the template's error.php, or do you see the server's generic error page? Or have you set up custom error pages?

The more relevant information we get, the better we can reproduce it.

Information required as stated in my previous comment.

In general, a Joomla site has as at least one menuItem and no matter where you are there is always an active menuItem. Can you describe in detail how you got this error?

This is probably some sort of bug due to migration issues. I am happy to prepare database dumps to illustrate the problem.

After migration, I have a few problems:

• Where it does not detect that the specified ItemId does not exist
• Index with com_finder returns red null or "Data too long for column 'route' at row 1"
• Does not process internal links in the content of articles and modules. [4.0] SEF don't works for urls in mod_custom #30818
• I did not disable old extensions (e.g. com_search) [4.0] Upgrade don't disable old extensions #30843

I confirm that.
It can also happen if you try to access an article without a sef url.
E.g. /index.php/component/content/article/70-quick-icons
