How to parse array of struct when creating stream in KSQL

Question

I'm trying to access a key called session ID, here is what the JSON of my message looks like:

{
   "events":[
      {
         "data":{
            "session_id":"-8479590123628083695"}}]}

This is my KSQL code to create the stream,

CREATE STREAM stream_test(
  
  events ARRAY< data STRUCT< session_id varchar> >
  
) WITH (KAFKA_TOPIC='my_topic', 
        VALUE_FORMAT='JSON')

But I get this error,

KSQLError: ("line 4:22: mismatched input 'STRUCT' expecting {'(', 'ARRAY', '>'}", 40001, None)

Does anyone know how to unpack this kind of structure? I'm struggling to find examples

Answer 1

My solution:

  events ARRAY< STRUCT<data STRUCT< session_id varchar >> >
