Bulk Import using nodeJS with Azure DocumentDB. Partition Key issue

I'm attempting to bulk import a lot of data into DocumentDB using Node. I've created the recommended stored procedure (the one that has been posted numerous times here and on MSDN). However, when I try executing it via Node, I get the following response: "Requests originating from scripts cannot reference partition keys other than the one for which client request was submitted."

The partitionKey on the Collection is "/id", and my request in Node looks like this:

client.executeStoredProcedure('dbs/blah/blah/sprocs/blah', [docs], {partitionKey: '/id'}, ...);

I can't find any concise documentation on this as it related to Node specifically. Has anyone encountered this issue and is there a solution? I'm completely open to the idea that I'm making a silly mistake, but this is my first rodeo, so to speak, with DocumentDB. Thank you all
