Site crash with php 8.0 Joomla 4.2.2 and Joomshopping 5.0.7

Site crash with php 8.0 Joomla 4.2.2 and Joomshopping 5.0.7

Hello again,
Still trying to migrate a live site using Joomla 3 and Joomshopping 4.x to Joomla 4 and Joomshopping 5.0.7.
As long as I stay with php 7.4 the site is OK. When I try to switch to php 8.0, the site crashes with the following error: "count(): Argument #1 ($value) must be of type Countable|array, null given".
The template producer apparently tracked this down to the login panel/operation but said he could not fix it due to copyright issues...
Is there anything you can do to help me out on this since end of life of php 7.4 is approaching quickly ?

Thanks and best regards

Philippe

OK...Investigated a bit more. It seems that the crash is located in the Joomla login panel which is not your problem...
However, if I disable the login panel module, the site comes up with the following warning:

Warning: Attempt to read property "type" on null in /homepages/5/d614854052/htdocs/web/moi/components/com_jshopping/Service/Router.php on line 53

I'll try to touch base with the Joomla 4 devteam for the crash issue...

Thx to let me know about the Router warning...
Cheers,

Philippe
