@stephenplusplus HALP!

[stephenplusplus]

I'm here, I'm here! Can you show the gcloud-node code that triggers this?

[richardkazuomiller]

It's hard to trace because the error stack trace doesn't show any of my code but I think I narrowed it down to this transaction

self.googleDataset.runInTransaction(function(transaction, done) {
      transaction.get(key, function(err, entity) {
        if (err) {
          try{
            transaction.rollback(done);
          }
          catch(e){
            _done(err)
          }
          return;
        }

        if(entity && entity.data){
          extend(entity.data,data)
        }
        else{
          entity = {
            key: key,
            data : data
          }
        }

        transaction.save(entity)

        done();
      });
    }, function(err) {

    });

This is the key path

[ 'ComradeServer', 'bfbf170a-782b-41d8-bef9-d01f3c5473d4' ]

and this is the entity

{ key: 
   Key {
     namespace: undefined,
     name: 'bfbf170a-782b-41d8-bef9-d01f3c5473d4',
     kind: 'ComradeServer',
     path: [Getter] },
  data: 
   { role: 'app',
     alive: true,

[stephenplusplus]

Reproduced. Working on a fix, I'll ping you when the PR is ready.

[richardkazuomiller]

Awesome. Thanks!

[stephenplusplus]

PR sent! #1206

v0.30.2 released!

I have the same error when trying to call datastore.get() passing an Array of 300+ Datastore keys. It works under 300 keys, is it a Protobuf limitation ? I think it opens too much network sockets

Reproduced. I'm going to open a new issue for this.

Hi, I am using grpc along with Node.js and facing similar issue:

Error: 13 INTERNAL: .employees.Empty#$__ is not a field: undefined

Facing this when trying call callback from server stub.
