Code sample not working in Azure CosmosDB with Gremlin

[kedzilla]

Code does not work in Azure CosmosDB, partition key is always needed when creating vertices.

g.addV('person').
  property('id', 'thomas.1').
  property('firstName', 'Thomas').
  property('lastName', 'Andersen').
  property('age', 44)

as stated in the documentation does not run successfully.

Error message from Azure:

Failure in submitting query: g.addV('person'). property('id', 'thomas.1'). property('firstName', 'Thomas'). property('lastName', 'Andersen'). property('age', 44): Script eval error: ActivityId : 11d3e271-6f6b-4999-ab30-0f1d5a1be41b ExceptionType : GraphRuntimeException ExceptionMessage : Gremlin Query Execution Error: Cannot add a vertex where the partition key property has value 'null'.

@kedzilla Thanks for your findings, I'm assigning this to the author for the feedback review.

@kedzilla, after reading through this article, I'm not sure if it recommends a partition key for this code sample.

I created a graph and used /lastName as the partition key and things worked fine.

What partition key did you use?

[seesharprun]

@kedzilla, we will update the article to indicate that you can use lastName as a partition key if you're following along with the samples.

[CodeLexis]

Essentially, in each vertex you add to the graph, you need a property that has the graph's partition key.

Example:

1. Create a Graph with a partition key /location, then

2. Create a vertex with property "location": g.addV("users").property("location", "united kingdom").property("name", "jackson").property("age", "30")
