tapioca dsl crashes with weird error when Gemfile contains OpenTelemetry gems.

[TwoAbove]

Hey! I'm instrumenting a ruby rails app with OpenTelemetry, and I noticed that just adding the

gem 'opentelemetry-sdk'
gem 'opentelemetry-exporter-otlp'
gem 'opentelemetry-instrumentation-all'

to the Gemfile causes tapioca dsl to crash with this weird error:

> bundle exec tapioca dsl
...
Error: `Tapioca::Dsl::Compilers::Protobuf` failed to generate RBI for `Google::Protobuf::AbstractMessage`
bundler: failed to load command: tapioca (/Users/seva/.asdf/installs/ruby/3.2.2/bin/tapioca)
/Users/seva/.asdf/installs/ruby/3.2.2/lib/ruby/gems/3.2.0/gems/tapioca-0.10.5/lib/tapioca/dsl/compilers/protobuf.rb:148:in `block in decorate': TypeError: Unexpected descriptor class: NilClass (Parallel::UndumpableException)
        from /Users/seva/.asdf/installs/ruby/3.2.2/lib/ruby/gems/3.2.0/gems/tapioca-0.10.5/lib/tapioca/rbi_ext/model.rb:40:in `block in create_class'
        from <internal:kernel>:90:in `tap'
...

(full stack trace here)

The weird thing is that we don't use google-protobuf, and adding it to the Gemfile doesn't help either.

Removing the OpenTelemetry gems from the Gemfile allows tapioca dsl to succeed.

I'm at a loss here as to what to do. I tried to find ways to ignore the OpenTelemetry gems, but couldn't find anything that works.

Any suggestions to what I can do here?

Thanks!

I did find this #1411 similar issue

Update: I noticed that the tapoica version in that issue was higher than ours, so I'll report back after I update tapioca 😅

Looks like just updating helped!
