Response has invalid UTF-8

[rajeshkmindix]

Hi,

I get the following error when trying to insert some nodes into dgraph.

com.google.protobuf.InvalidProtocolBufferException: Protocol message had invalid UTF-8.

I narrowed it down to

`ManagedChannel channel = ManagedChannelBuilder.forAddress("localhost", 9080).usePlaintext(true).build();
DgraphGrpc.DgraphBlockingStub blockingStub = DgraphGrpc.newBlockingStub(channel);
DgraphClient dgraphClient = new DgraphClient(Collections.singletonList(blockingStub));

for(int i = 0; i < 1000; i++) {
  JsonObject json = new JsonObject();
  json.addProperty("id", i);
  json.addProperty("name", "abcdefgh" + i);

  System.out.println("for " + i);
  Mutation mu =
          Mutation.newBuilder()
                  .setCommitImmediately(true)
                  .setSetJson(ByteString.copyFromUtf8(json.toString()))
                  .build();
  dgraphClient.newTransaction().mutate(mu);
}`

After inserting around 100 to 150 nodes. I get the above error. If I rerun the above code, I get the same error for the first record itself. Every subsequent mutation request gets the same error.

I installed using
curl https://get.dgraph.io -sSf | bash

Ran it using
dgraph zero --port_offset -2000 dgraph server --memory_mb 2048 --zero localhost:5080
Need help with this.

Thanks in advance,
Rajesh
