I want to create a custom tab in admin category_from page. After create custom tab i want to call a phtml file.

I have successfully created a custom tab in category_form but when i try to call a block it gives me an error showing

a:4:{i:0;s:94:"The requested component ("block") is not found. Before using, you must add the implementation.";i:1;s:7167:"#0 /var/www/practice/vendor/magento/module-ui/Model/Manager.php(207): Magento\Framework\View\Element\UiComponent\Config\Provider\Component\Definition->getComponentData('block')

This what i have done

category_form.xml

    <?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">

Your category_form.xml Vendor/Module/view/adminhtml/ui_component/category_form.xml should be

<?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <fieldset name="custom_fieldset">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="label" xsi:type="string" translate="true">Custom Tab</item>
                <item name="collapsible" xsi:type="boolean">true</item>
                <item name="sortOrder" xsi:type="number">140</item>
            </item>
        </argument>
        <container name="custom_fieldset_container" >
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="sortOrder" xsi:type="number">200</item>
                </item>
            </argument>
            <htmlContent name="html_content">
                <argument name="block" xsi:type="object">Vendor\Module\Block\Adminhtml\Category\Custom</argument>
            </htmlContent>
        </container>
    </fieldset>
</form>

Now create Vendor/Module/Block/Adminhtml/Category/Custom.php

namespace Vendor\Module\Block\Adminhtml\Category;

class Custom extends \Magento\Backend\Block\Template
{
    /**
     * Block template
     *
     * @var string
     */
    protected $_template = 'custom.phtml';
}

And create template Vendor/Module/view/adminhtml/templates/custom.phtml

<h1>Custom Tab Content</h1>
