How would I use the REST api to create a node with xrefs in one call?

Omar Mir

I seem to be able to run the query on the nodes endpoint with the following body:
{

type: 144,

parent_id: 48061438,

name: 'test',

roles: {

categories: {

'25953013_3': ['aaa'],

'25953013_2': ['bbb'],

'25953013_4': ['ccc']

},

xrefs: {

xref_type: "XREF",

xref_id: 2829282882

}

}

}

But the server responds with an error noting that I need to select an object to reference. I clearly have the format wrong. Help would be appreciated!
