Today I had to fix the following issue in a custom module. The error appeared on the UI Component list view.

Fatal error: Method Magento\Ui\TemplateEngine\Xhtml\Result::__toString() must not throw an exception, caught TypeError: Argument 1 passed to Magento\Framework\View\Element\UiComponent\DataProvider\DataProvider::searchResultToOutput() must implement interface Magento\Framework\Api\Search\SearchResultInterface, instance of [Namespace]\[Module]\Model\ResourceModel\Team\Collection given, called in

Fatal error: Method Magento\Ui\TemplateEngine\Xhtml\Result::__toString() must not throw an exception, caught TypeError: Argument 1 passed to Magento\Framework\View\Element\UiComponent\DataProvider\DataProvider::searchResultToOutput() must implement interface Magento\Framework\Api\Search\SearchResultInterface, instance of [Namespace]\[Module]\Model\ResourceModel\Team\Collection given, called in

I found the reason of the problem in the di.xml file. All what was missing was the following virtualType node. After adding this and re-compiling the code, the list view was fixed.

<virtualType name="[Namespace]\[Module]\Model\ResourceModel\Team\Collection" type="Magento\Framework\View\Element\UiComponent\DataProvider\SearchResult">
    <arguments>
        <argument name="mainTable" xsi:type="string">[namespace]_[module]_team</argument>
        <argument name="resourceModel" xsi:type="string">[Namespace]\[Module]\Model\ResourceModel\Team</argument>
    </arguments>
</virtualType>

<argument name="mainTable" xsi:type="string">[namespace]_[module]_team</argument>

<argument name="resourceModel" xsi:type="string">[Namespace]\[Module]\Model\ResourceModel\Team</argument>

</arguments>

</virtualType>

Today I created a new listing for a custom module, but unfortunately all what I got was the error message below.

Not registered handle [namespace]_[module]_team_index_data_source

1	Not registered handle [namespace]_[module]_team_index_data_source

After digging around for few minutes I noticed the above handler was actually missing in the di.xml file. I simply added the following collections argument and re-compiled the code.

<type name="Magento\Framework\View\Element\UiComponent\DataProvider\CollectionFactory">
    <arguments>
        <argument name="collections" xsi:type="array">
            ...
            <item name="[namespace]_[module]_team_index_data_source" xsi:type="string">[Namespace]\[Module]\Model\ResourceModel\Team\Collection</item>
            ...
        </argument>
    </arguments>
</type>

...

<item name="[namespace]_[module]_team_index_data_source" xsi:type="string">[Namespace]\[Module]\Model\ResourceModel\Team\Collection</item>

...

</argument>

</arguments>

</type>

All good!
