Can't find the alive key

[saiqulhaq-hh]

Hello,
I've encountered an issue in my Sidekiq logs. I'm seeing the following error message repeated 74 times in the last 3 hours:

{"severity":"ERROR","message":"Can't find the alive key","@timestamp":"2024-11-21T12:00:36.165Z","@version":"1"}

I'm concerned about this error and wondering if it indicates a problem with my configuration.
However I found that it is written in the spec

sidekiq_alive/spec/server/rack_spec.rb

Line 30 in a531833

expect(last_response.body).to(eq("Can't find the alive key"))

But could you please help me understand:
What might be causing this "Can't find the alive key" error?
Is this a critical issue that could affect my Sidekiq's functionality?
Are there any specific configuration settings I should check or adjust to resolve this?
Any guidance you can provide would be greatly appreciated. Thank you for your time and assistance.

Best regards,
Saiqul Haq
