Unable to add defs to DescriptorPool: out of memory (Google::Protobuf::TypeError)

[bilby91]

Hello,

I'm running an issue when trying to start a rails server after adding the gem in the project. It seems to be related to the following issues but I haven't been able to figure out a workaround yet.

Related issues:

• Unable to add defs to DescriptorPool: Symtab already has a def named ruby-protobuf/protobuf#381
• Optional require_relative in Ruby generated code protocolbuffers/protobuf#2478

The stacktrace:

bash-5.0# bundle exec rails s -b 0.0.0.0

Thanks before hand!

Thanks for the report! Is there any chance you can provide a repro case in the form of a repo?

Will see if I can reproduce it outside of my project!
