php - problems with slim loading class

one text

Solution:

There's no error here about class loading issues. You've defined a route with a callable that isn't valid:

/**
 * @param mixed $resolved
 * @param mixed $toResolve
 *
 * @throws RuntimeException
 *
 * @return callable
 */
private function assertCallable($resolved, $toResolve): callable
{
    if (!is_callable($resolved)) {
        throw new RuntimeException(sprintf(
            '%s is not resolvable',
            is_callable($toResolve) || is_object($toResolve) || is_array($toResolve) ?
                json_encode($toResolve) : $toResolve
        ));
    }
    return $resolved;
}

The error complaints about CitasController:getAll() but you have public function getAall($request, $response, $arg).
