C++ and JS compatability

[SvenGebert]

protobuf.js version: 7.3.0, C++ protobuf version 21.4

Is it acutally possible to decode cpp-encoded protobuf objects with protobufs.js 7.3.0 and vice versa?
Currently C++ protobuf version 21.4 and protobuf.js version: 7.3.0 are not working well, the generated buffers are quite different.
Is it likely to work with the newest C++ version 27.0?

Have you tried encoding with one and decoding with the other?

The protobuf spec allows for some variance in how a message can be represented; in particular, the fields can be serialized in any order. As a result, very different looking buffers can represent the exact same message.

Hey, thanks for your quick response!

Yeah I've encoded a message with c++ and were able to decode it on the javascript side by adding 2 missing header bytes and what seems like padding at the end. Vice versa is just not possible. And it seems like there is no tolerance in encoding right now. I ll try updating the c++ version tho!
If anyone has idea please comment!
