"No snapshots exist" with snapshots enabled

[Traver72]

With the following configuration (development environment)

Rack::MiniProfiler.config.snapshot_every_n_requests = 1
Rack::MiniProfiler.config.storage = Rack::MiniProfiler::RedisStore

I made sure that RedisStore was working properly by checking that the rest was working and stored in Redis.
Either "snapshot_every_n_requests" is not triggered correctly or the snapshot cannot be created.
I use macos with apple m1 if that makes a difference.

There is nothing in the logs that would be helpful in troubleshooting.
