Since HttpFoundation ^6.0, InputBag::get() must return scalar values.
A call to AbstractAdmin::getFilterParameters() may return an array.

The fix would be to change $this->getRequest()->query->get('filters') into $this->getRequest()->query->all('filters'), which may return an array.

[VincentLanglet]

$this->getRequest()->query->all('filters')

always look for array, which is not the case.

One solution would be $this->getRequest()->query->all()['filters'].

But I don't see why the filters would be an array.

We're using

• filter for the filters
• filters to reset it

$filters = $bag->all('filter');
if ('reset' === $this->getRequest()->query->get('filters')) {

Maybe you're misusing the param ?
