seems about comments

after removed all comments, no errors

[njooma]

I'm seeing the same issue as well. I can't remove comments from the protos as I don't own them (I'm using buf to grab the proto definitions).

Downgrading from 21.1.x back down to 21.0.2 works for now.

Bug fix released with protoc_plugin 21.1.2.
