TypeError: Unable to resolve type 'uint8_t'

[goromlagche]

While trying to use ffi inside a docker image built from arm64v8/ruby:3.2.2 I am getting an issue TypeError: Unable to resolve type 'uint8_t' . The gem install works fine and passes.

I tried running rake types_conf from inside the container and this is the git diff I am getting.

I ran the rake task on current master branch.

Any inputs on how to go about solving this?

Same here, @goromlagche

I'm using ruby:3.0.6-slim-bullseye image for arm64 and hitting this issue when running it, not installing gems

• ffi: 1.16.3
• karafka-rdkafka: 0.14.1

=> karafka/karafka-rdkafka#54 - so upgrading karafka-rdkafka worked for me.
