Typo3 8.7: wrong redirect to landing page when using link action

I'm currently having trouble calling an action from a view using this link action

<f:link.action controller="Checklist" action="duplicate" arguments="{checklist: checklist}" class="clone"> <i class="fa fa-files-o" aria-hidden="true"></i> </f:link.action>

Instead of calling the action and running the code, the plugin simply redirects to the landing page of my website without throwing any errors.

I have never had this problem, other actions in the checklist controller can be called without any problem (!from the same view!).

Even when I change the Action code to this:

public function duplicateAction(\Vendor\someExt\Domain\Model\Checklist $checklist) {    
  \TYPO3\CMS\Core\Utility\DebugUtility::debug($checklist);
  exit; 
}

it simply ignores all the code and redirects anyway.

I have added the action (like any other) inside the ext_localconf to configurePlugin to the callable Actions for the controller checklist.

Thanks for your help.

I found the solution to my problem myself. The problem was none-Typo3 related as it was Javascript code that intervened in the submitting process of the link action which lead to the redirect..
