RedisClient::CommandError on retry

[bellef]

Hi and first of all thank you for your hard work on this gem! ❤️

My problem

I'm having trouble retrying jobs using sidekiq UI. Whenever I navigate to /sidekiq/retries and click on Retry Now, I get a 500 with the following:

So it's a RedisClient::CommandError with the message "ERR syntax error".
If I set a breakpoint before the command is sent, here is what's going on:

["SCAN", "0", "0", "match", "activejob_uniqueness:path/to/job:3aa7381f4be2b444874cacf24f6c5c9e*"]

And it's coming from:

redis-client (0.20.0) lib/redis_client/connection_mixin.rb:35:in `call'
redis-client (0.20.0) lib/redis_client.rb:257:in `block (2 levels) in call'
redis-client (0.20.0) lib/redis_client/middlewares.rb:16:in `call'
redis-client (0.20.0) lib/redis_client.rb:256:in `block in call'
redis-client (0.20.0) lib/redis_client.rb:677:in `ensure_connected'
redis-client (0.20.0) lib/redis_client.rb:255:in `call'
redis-client (0.20.0) lib/redis_client.rb:639:in `scan_list'
redis-client (0.20.0) lib/redis_client.rb:359:in `scan'
activejob-uniqueness (0.3.1) lib/active_job/uniqueness/lock_manager.rb:28:in `each'
activejob-uniqueness (0.3.1) lib/active_job/uniqueness/lock_manager.rb:28:in `block (2 levels) in delete_locks'
[...]

Which is the following line:

conn.scan(0, match: wildcard).each { |key| conn.call('DEL', key) }

What am I missing? (I'm pretty sure it's kind of obvious so apologies if it is).
Thank you in advance for your help 🙏
