Conflict between microsoft_kiota_faraday (Kiota SDK) and Sidekiq 8.1 in Rails 8 app

Environment:

Ruby 3.4
Rails 8.1
Sidekiq 8.1
Trying to use Kiota SDK (microsoft_kiota_abstractions + microsoft_kiota_faraday + microsoft_kiota_authentication_oauth) for Microsoft Graph

Problem:
When adding the Kiota gems, Bundler fails with dependency conflicts (mainly in faraday, concurrent-ruby, or adapters), preventing the server or Sidekiq from booting.

Examples of typical errors observed:

Gem::ConflictError: unable to activate X (required by Kiota) because Y (required by Sidekiq 8.1) conflicts
Runtime errors related to thread-safety or multi-handle in Faraday

Attempts made:

bundle update
Downgrade Sidekiq to ~7.3 (works, but not ideal)
Lazy require of Kiota gems within the service (partially mitigates, but does not resolve global boot)

Impact:
Prevents the use of the official Kiota SDK in Rails 8 + Sidekiq 8.1 apps without downgrades or heavy workarounds.

Suggestion:

Check compatibility of Kiota gems with Sidekiq 8.x

Consider adding a Faraday version constraint or adapter to coexist with Sidekiq

Reproducible environment:
Rails 8.1 + Sidekiq 8.1 + gem 'microsoft_kiota_faraday'

Thank you!

Start by reproducing Bundler resolution in the stated Ruby 3.4, Rails 8.1, and Sidekiq 8.1 environment with microsoft_kiota_faraday, then record the exact dependency or runtime conflict. Done means identifying a confirmed compatibility issue or dependency constraint that allows the Kiota gems and Sidekiq to boot together without downgrading Sidekiq.
