Custom admin UI component grid breaks when collection is not AbstractDb

[zaximus84]

Preconditions (*)

1. Install Magento 2.4.2
2. Build a custom admin grid using UI components and a data provider.
3. Use a collection for your data provider that extends Magento\Framework\Data\Collection, but not Magento\Framework\Data\Collection\AbstractDb.

Steps to reproduce (*)

1. Attempt to view the grid in admin.

Expected result (*)

1. The grid displays without error.

Actual result (*)

1. This error occurs: Call to undefined method {custom collection class}::getSelect()
   Exception in /var/www/html/vendor/magento/framework/View/Element/UiComponent/DataProvider/FilterPool.php:45

This issue was introduced in 2.4.2 due to changes in the FilterPool class. See this commit: 2638e0f

The applyFilters method type hints that the $collection argument can be an instance of Magento\Framework\Data\Collection or Magento\Framework\Data\Collection\AbstractDb, but the method executes operations that are only guaranteed on AbstractDb (i.e. getSelect).

Any AbstractDb operations should only be executed after some sort of type check to prevent errors for collections that don't extend that abstract. As an example, I built an admin grid that populates data from a remote API and has no need of a database select object, so it doesn't extend AbstractDb.

The exact same problem was discovered in baldwin-agency/magento2-module-url-data-integrity-checker#16

If you wrap that contents of that applyFilters method in something like the following, it no longer crashes, but I have no idea if that would be considered a good solution:

public function applyFilters(Collection $collection, SearchCriteriaInterface $criteria)
{
    if (method_exists($collection, 'getSelect')) {
        ...
    }
}

But the type checking on AbstractDb could be a solution as well...

@engcom-Golf: what do you think might be a good solution here?

Hello. Faced this issue when going to Report->Braintree Settlement grid. And I can reproduce this problem on a clean Magento 2.4.2 installation!

This issue has been automatically marked as stale because it has not had recent activity. It will be closed after 14 days if no further activity occurs. Is this issue still relevant? If so, what is blocking it? Is there anything you can do to help move it forward? Thank you for your contributions!

Issue is definitely not stale, leaving a comment to not close it.

@Den4ik: can we get somebody to review this and propose a solution? I'm willing to create a PR for this if a good solution can be proposed, thanks!

We needed to add a silly workaround to keep our module working on 2.4.2 because of this bug: https://github.com/baldwin-agency/magento2-module-url-data-integrity-checker/pull/17/files

I confirm that the error is still valid. All magento 2.4.2 stores have this bug when going to Report->Braintree Settlement grid.
