Hi there, i'm trying to setup Wire with grpc so I have proto files generating code but there is a `Type mismatch: inferred type is Long? but Any was expected` error on the `Long?` type in generated methods that look like this `override fun ReadPost(): GrpcCall&lt;Long?, Post&gt; =...`  (from `rpc ReadPost(google.protobuf.UInt64Value) returns (Post) {}`)
I dont understand what's going on and I can't seem to find anything on SO or anywhere. It's the first time I use this kinda stuff so maybe I forgot something silly ?

after investigating more, I'm lost because all "wrapper values" seem to be mapped to nullables, for ex:  `UINT64_VALUE: ProtoAdapter&lt;Long?&gt;` but `GrpcCall` doesn't accept nullables: `interface GrpcCall&lt;S : Any, R : Any&gt;`

ok so replacing all `google.protobuf.UInt64Value` by a redefined `CustomUInt64Value { uint64 value = 1; }` works but it seems weird to me
is this a bug i should file somewhere ?

Yeah, filing an issue on GitHub would be nice, thanks!

ok i just did :slightly_smiling_face:
