Aerospike, NodeJS. Pushing into array in object

Question

I need to push some data in array, that stored in object Example. Bin, that I get

db.get(key) // -> { a: 'b', b: { c: [] } }

I need to push into b.c, but I can't, because of error

db.operate(key, [Aerospike.lists.append('b.c', 1)]) // -> AerospikeError: no operations defined

Can it be solved or I can't do it?

As @pgupta correctly pointed out, you need to set the CDT context to operate on nested lists/maps. With the Node.js client, you use the ListOperation#withContext function to set the context:

db.put(key, { a: 'b', b: { c: [] } })
db.operate(key, [
  Aerospike.lists.append('b', 1)
    .withContext((ctx) => ctx.addMapKey('c'))
])
db.get(key) // => { a: 'b', b: { c: [1] } }
