Drupal\Core\Security\UntrustedCallbackException: Render #pre_render callbacks must be methods of a class that implements \Drupal\Core\Security\TrustedCallbackInterface or be an anonymous function. <strong>The callback was Drupal\imce\ImceFileField::preRenderWidget</strong>. See https://www.drupal.org/node/2966725 in Drupal\Core\Render\Renderer->doTrustedCallback() (line 96 of /srv/www/htdocs/kacb9/web/core/lib/Drupal/Core/Security/DoTrustedCallbackTrait.php).
This is on Drupal 9.0 on a Linux platform. Help please.
Sorry, I submitted two of these by accident. See no way to remove a duplicate!

hodowany commentedI followed the advice from the error message and copied the procedure outlined in https://www.drupal.org/node/2966725 to change the preRenderWidget callback to implement the TrustedCallbackInterface interface. The modification is on the class ImceFileField in the file
/modules/imce/src/ImceFileField.php
class declaration is changed to:
class ImceFileField implements TrustedCallbackInterface {
then add the trusted callback method inside the class
public static function trustedCallbacks() {
return ['preRenderWidget'];
}
That's it. Security error gone. I will attach a diff/patch file below.
