Hello,

I do not understand how to use set\_json as to indicate in the wiki ([https://docs.dgraph.io/mutations/#setting-literal-values](https://docs.dgraph.io/mutations/#setting-literal-values)).

With Ratel (on HTTP port) I have an error “empty mutation” when using

{“set\_json”:  
{  
“name”: “Alice”  
}  
}

while

{“set”:  
{  
“name”: “Alice”  
}  
}

works!

I wonder if set\_json is really supported in 1.0.7. That would explain why the JavaClient which generates set\_json syntax too (with a Mutation.newBuilder().setSetJson().build() on gRPC port) answers me “io.grpc.StatusRuntimeException: ABORTED: Transaction has been aborted”

PS: [Update: Using JSON to mutate on Dgraph. (cURL, Raw HTTP)](http://discuss.hypermode.com/t/update-using-json-to-mutate-on-dgraph-curl-raw-http/2863) examples use set syntax too 😕

set\_json is an operation used by clients (native), So this syntax you are confusing is via HTTP Raw tho

Thank you, It allowed me to understand that the error produced by my Java code didn’t come from the use of set\_json by native Java client.  
In fact, I forgot (!) to commit the transaction and it is the normal message of the discard contained in the finally clause…  
Sorry
