TYPO3 Core

Using extbase variables in a FLUIDTEMPLATE content object leads to following exception:

ArgumentCountError
Too few arguments to function TYPO3\CMS\Extbase\Mvc\Web\RequestBuilder::build(), 0 passed in /var/www/html/typo3/sysext/frontend/Classes/ContentObject/FluidTemplateContentObject.php on line 284 and exactly 1 expected

Example setup to test:

Typoscript

page = PAGE
page {
  typeNum = 0
  10 = COA_INT
  10 {
    10 = FLUIDTEMPLATE
    10 {
      file = fileadmin/templates/form.html
      settings {
        persistenceIdentifier = fileadmin/form_definitions/contact.form.yaml
      }
      extbase.pluginName = Formframework
      extbase.controllerExtensionName = Form
      extbase.controllerName = FormFrontend
      extbase.controllerActionName = perform
    }
  }
}
