Magento 2.3.3 Admin issue

[lamda]

If you delete the following block from the UI Component xml file, things appear to be working normally for me:

<argument name="context" xsi:type="configurableObject"> <argument name="class" xsi:type="string">Magento\Framework\View\Element\UiComponent\Context</argument> <argument name="namespace" xsi:type="string">prince_faq_index</argument> </argument>

just add to app/etc/di.xml
<item name="2" xsi:type="string">Magento\Framework\View\Element\UiComponent\ContextInterface</item>

 <type name="Magento\Framework\View\Element\UiComponent\Argument\Interpreter\ConfigurableObject">
        <arguments>
            <argument name="classWhitelist" xsi:type="array">
                <item name="0" xsi:type="string">Magento\Framework\Data\OptionSourceInterface</item>
                <item name="1" xsi:type="string">Magento\Framework\View\Element\UiComponent\DataProvider\DataProviderInterface</item>
                <item name="2" xsi:type="string">Magento\Framework\View\Element\UiComponent\ContextInterface</item>
            </argument>
        </arguments>
    </type>

Could you explain what you mean by that? Why is not good? And any pointers on how one could add that to di.xml?

[mrtuvn]

delete is not good way. Add di.xml for whitelist class instead

[lamda]

Does anyone have any pointers on how to solve this?

[hidonet]

@lamda yes. it's worked for me too. Thanks.

Why do we need to delete these rows? What is changed in the last version of Magento?

[ilnytskyi]

Or just implement Magento\Framework\Data\OptionSourceInterface for that Context class

[DylanHopman]

@lamda got the right fix for it. You can find the file in your module -> etc/view/adminhtml/ui_component

[jithutj]

just add to app/etc/di.xml
<item name="2" xsi:type="string">Magento\Framework\View\Element\UiComponent\ContextInterface</item>

 <type name="Magento\Framework\View\Element\UiComponent\Argument\Interpreter\ConfigurableObject">
        <arguments>
            <argument name="classWhitelist" xsi:type="array">
                <item name="0" xsi:type="string">Magento\Framework\Data\OptionSourceInterface</item>
                <item name="1" xsi:type="string">Magento\Framework\View\Element\UiComponent\DataProvider\DataProviderInterface</item>
                <item name="2" xsi:type="string">Magento\Framework\View\Element\UiComponent\ContextInterface</item>
            </argument>
        </arguments>
    </type>

Thank You its working!!!

I added this to an over ride di.xml file and its resolved the issue. I wasnt sure if app/etc/di.xml would be over ridden in future core magento updates. Can someone explain a little about what the above is doing?
