Having trouble with dynamic JSON values and translating that into POJO classes. My retrofit2 response comes up with null so I assume my structuring is wrong.
My expected JSON output:
`

"Meta Data": {
"1. Information": "Intraday (5min) open, high, low, close prices and volume",
"2. Symbol": "IBM",
"3. Last Refreshed": "2022-10-26 19:40:00",

"6. Time Zone": "US/Eastern"
},
"Time Series (5min)": {
"2022-10-26 19:40:00": {
"1. open": "135.0600",

My retrofit2 enqueue responsebody for metadata works but when i look towards the TimeSeries it produces null results. I followed this: Gson.fromJson, how to use dynamic json value on my POJO class? , as it had similar JSON structuring of dynamic keys but to no avail. I am using GSON library and do not wish to use Jackson.
Thanks.
