It seems works on the latest Lua-protobuf version (HEAD of this repo).

It seems works on the latest Lua-protobuf version (HEAD of this repo).

Yes, I tried HEAD, it works, but 0.3.4 does not.

[starwing]

Yes, it fixed at https://github.com/starwing/lua-protobuf/commit/477581fb2ef50dfe3988896f03cd93ac0b8aef50
