Using 3.5.14 Neo4J and using all 3.5.14 Jars for plugins  
I am getting the NullPointerException when I call ga.nlp.annotate. I followed the instructions from [GitHub - graphaware/neo4j-nlp: NLP Capabilities in Neo4j](https://github.com/graphaware/neo4j-nlp)

```auto
MATCH (n:News)
CALL ga.nlp.annotate({text: n.text, id: id(n)})
YIELD result
MERGE (n)-[:HAS_ANNOTATED_TEXT]->(result)
RETURN result

```

Error:Failed to invoke procedure `ga.nlp.annotate` : Caused by: java.lang.RuntimeException: No pipeline null

Hi!

Have you set a default pipeline?

```auto
CALL ga.nlp.processor.pipeline.default("my_pipeline")

```

Otherwise, I think you need to add an extra parameter in `ga.nlp.annotate`:

```auto
MATCH (n:News)
CALL ga.nlp.annotate({
     text: n.text, 
     id: id(n), 
     //checkLanguage: false, 
     pipeline : "my_pipeline"
}) YIELD result
MERGE (n)-[:HAS_ANNOTATED_TEXT]->(result)

```

In both cases, the pipeline "my\_pipeline" was added using the `ga.nlp.processor.addPipeline` procedure.

I have tried adding a default pipeline,

#### Neo.ClientError.Procedure.ProcedureCallFailed

Alright, you can check that there is a pipeline named "my\_pipeline" with

`CALL ga.nlp.processor.getPipelines()`

Otherwise, I don't have other ideas to explain this error for now ☹

Java should test for a Null and then report some useful error msg.

The fact that some problem is occurring (and not gracefully handled) in the Java implementation is a bug which has been reported here: [Failed to invoke procedure `ga.nlp.annotate`: Caused by: java.lang.RuntimeException: No pipeline null · Issue #159 · graphaware/neo4j-nlp · GitHub](https://github.com/graphaware/neo4j-nlp/issues/159)
