Possible error sources
======================

configurePlugin: Actions declared incorrectly
---------------------------------------------

This error happens when the first array does have an integer as key
instead of the plugin name:

.. container::

   ::

      array('show')

The correct solution is this:

.. container::

   ::

      \TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
          'FooExt',
          'PluginName',
          [\Foo\Ext\Controller\PluginController::class => 'show'],
          [\Foo\Ext\Controller\PluginController::class => 'show'] // non-cacheable actions
      );
