DiezNobach opened a new issue, #40018: URL: https://github.com/apache/beam/issues/40018
### What happened? Affects: Apache Beam Go SDK v2.75.0 (also confirmed present on master as of 2026-09-04, via code search). Go 1.26 toolchain, but this is independent of Go version — it's a go build/module-resolution failure caused by upstream package removal. sdks/go/pkg/beam/io/pubsubio/pubsubio.go imports google.golang.org/genproto/googleapis/pubsub/v1 (aliased pb) solely to use pb.PubsubMessage as a plain proto struct for local (un)marshaling — no gRPC client from that package is used. pubsubio.Read/.Write delegate entirely to Dataflow's native beam:transform:pubsub_read/write:v1 external transform, so this import isn't functionally required for either. Recent google.golang.org/genproto releases no longer contain the googleapis/pubsub/v1 package at all. Any Go module that (a) imports beam/io/pubsubio and (b) needs — directly or transitively — a genproto version released after that package was dropped, fails to build. Steps to reproduce: In a Go module, import github.com/apache/beam/sdks/v2/go/pkg/beam/io/pubsubio. ### Issue Priority Priority: 2 (default / most bugs should be filed as P2) ### Issue Components - [ ] Component: Python SDK - [ ] Component: Java SDK - [x] Component: Go SDK - [ ] Component: Typescript SDK - [x] Component: IO connector - [ ] Component: Beam YAML - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Infrastructure - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Prism Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
