Argument #1 ($redis) must be of type Redis, Predis\Client given

@bobburns I have new version of the module ready if you would be willing to try it. I didn't make the release yet, waiting to get some feedback first but code should be stable and usable.

New version supports both Redis PECL extensions as well as Predis PHP package. In addition you can also chose to use APCu or Memcached. Up to date documentation can be found in the README file: https://git.drupalcode.org/project/crawler_rate_limit/-/blob/2.x/README.md

You can install this version and all dependencies (Predis package and Redis module) with the following commands:


composer require predis/predis:^1.1.1 drupal/redis drupal/crawler_rate_limit:2.x-dev@dev
drush en redis crawler_rate_limit


I tested this version with Drupal 9 and 10 and PHP 7.4 and 8.1.

Version 2.1-beta1 of module introduced a lot of changes and improvements and hopefully this issue is not relevant anymore.
