Fix error: RedisClient::ReadTimeoutError (GEMFILE-DIRECTORY-11)

[revise-dev]

The error RedisClient::ReadTimeoutError: Waited 1.0 seconds is occurring due to a conflict between Sentry's Redis instrumentation and Sidekiq's Redis client. To resolve this, we need to disable Sentry's Redis instrumentation specifically.

The change involves adding a single line to the Sentry configuration in the config/initializers/sentry.rb file. This line tells Sentry to skip instrumenting Redis operations:

config.rails.skippable_instrumentations += %w[redis]

By adding Redis to the list of skippable instrumentations, we prevent Sentry from wrapping Redis operations with its own instrumentation code. This allows Sidekiq to interact with Redis directly, avoiding the timeout issue.

The original intent of the Sentry configuration was to set up error tracking and performance monitoring for the application. By default, Sentry instruments various parts of a Rails application, including Redis operations, to provide comprehensive monitoring. However, in this case, the Redis instrumentation is causing conflicts with Sidekiq's own Redis client usage.

This change maintains the overall functionality of Sentry for error tracking and performance monitoring while specifically excluding Redis operations from its instrumentation. This should resolve the timeout error without compromising the overall monitoring capabilities of Sentry for the rest of the application.
