This does seem to be the issue. I found two different protoc binaries in the bazel cache of my Envoy build. One is the correct version (26.1) and the other is version 24.4. Somehow the version 24.4 binary must be getting used to generate the files instead of the version 26.1 binary.
Thank you very much.
