What waterdrop version are you using? Can you create a small repro script?

What waterdrop version are you using? Can you create a small repro script?

I did not manually install Waterdrop. It got installed with karafka.
Anyway the issue was with version mismatch of Rails and karafka. This issue is there in Rails 5 and Karafka 1.3. It got solved once I downgraded my Karafka version to 1.2.12.
Similarly, Karafka 1.3 works fine with Rails 6.

I would still want to fix it for Rails 5 and Karafka 1.3. Could you create an example repro repo?

mark_as_consumed! method is not available in 1.2.12. Is there another method similar to this?

I see you're satisfied with the answer. Closing :)

It's bootsnap issue with ruby-2.5 and iseq compile cache enabled (at least it was in my case).
See Shopify/bootsnap#257.
