i get the same problem with you. i found that my protoc version is too new. then i remove the "github.com/grpc-ecosystem/grpc-gateway" from vendor folder. and do this:

go get -u -v github.com/grpc-ecosystem/grpc-gateway

after that, i fixed this problem.

@utopiaprince would you be able to send a PR to update the vendor dir?

[graphaelli]

Ran into this too but don't see a vendor so sent a PR to update the code instead.
