Failed to load Wasm module due to a missing import: wasi_snapshot_preview1.fd_filestat_get

[ohadvano]

Describe the bug / error

When I am trying to use the following package: "google.golang.org/protobuf/proto"
And in particular:

func (ctx *setBodyContext) OnHttpRequestBody(bodySize int, endOfStream bool) types.Action {
    _ = proto.String("x")
    return types.ActionContinue
}

I get the following error during Envoy startup:
Failed to load Wasm module due to a missing import: wasi_snapshot_preview1.fd_filestat_get

When I give up this package the error is gone and the module loads successfully.
