Bug description

Twig errors are not always helpful

Example:

[2024-09-30 13:44:37] glpiphplog.CRITICAL:   *** Twig Error (Twig\Error\RuntimeError): "An exception has been thrown during the rendering of a template ("htmlspecialchars(): Argument #1 ($string) must be of type string, array given")." in template "/var/www/html/fix95/templates/pages/admin/assetdefinition/fields_display.html.twig" at line 88

  public/index.php:58                                Symfony\Component\HttpFoundation\Response->send()

The referred line in the template has no such call to htmlspecialchars. Instead, it is a macro call for fields.dropdownArrayField.
I don't know why the Twig error backtrace ends here, but the information in $error->getPrevious() is far more useful and isn't logged anywhere.

The previous error correctly shows it is a TypeError in Dropdown line 2422 due to an incorrectly formatted elements parameter.
