### Fixed
- Fix possible null error in search

[VincentLanglet]

It's not clear where there is an issue with the fact query can be null in the template https://github.com/sonata-project/SonataAdminBundle/blob/4.x/src/Resources/views/Core/search.html.twig

[core23]

It is an issue, I got several exception in my projects.

In the template we only check if the query variable is defined and not false. A null value is a defined value so the blocks are rendered.

What is the exception you get ?

The block result doesn't seems to use the query variable
https://github.com/sonata-project/SonataAdminBundle/blob/4.x/src/Resources/views/Block/block_search_result.html.twig

In the template we only check if the query variable is defined and not false. A null value is a defined value so the blocks are rendered.

'' value will also be defined so block will be rendered in the same way.

Also, it's kinda weird to have this defined and not false check, since we use query in the translation too.

it was made in #1855
Shouldn't we just update the template to if query is not null ?

Btw if you rebase, I fix the phpstan/rector build

Done

I appreciate you re-request my review but I have a lot of question unanswered...

I receive a TypeError, as the null value is passed from the template to the SearchHandler:

To be safe we could fix it in the template as well, but this won't help if you are using a custom template. The root cause is the block, not the template.
