Confused how to make a twig function

Try changing

public function getFunctions()

To

public function getFunctions(): array

Your getFunctions() declaration must match the extended getFunctions()

github.com

getgrav/grav/blob/develop/system/src/Grav/Common/Twig/Extension/GravExtension.php#L175

    
      
                  new TwigFilter('count', 'count'),
                  new TwigFilter('array_diff', 'array_diff'),
              ];
          }
          
          
/**
           * Return a list of all functions.
           *
           * @return array
           */
          public function getFunctions(): array
          {
              return [
                  new TwigFunction('array', [$this, 'arrayFilter']),
                  new TwigFunction('array_key_value', [$this, 'arrayKeyValueFunc']),
                  new TwigFunction('array_key_exists', 'array_key_exists'),
                  new TwigFunction('array_unique', 'array_unique'),
                  new TwigFunction('array_intersect', [$this, 'arrayIntersectFunc']),
                  new TwigFunction('array_diff', 'array_diff'),
                  new TwigFunction('authorize', [$this, 'authorize']),
                  new TwigFunction('debug', [$this, 'dump'], ['needs_context' => true, 'needs_environment' => true]),

That’s basically what the error says. Docs probably are a bit outdated
