Hi Jack,
Thanks for getting back to me.
I found that in Databricks when I make the request I need to pass stream:true in the JSON body.
I found on another discussion on the retool forum which says that to do streaming I'd have to write a custom component.
For reference: Stream server-sent events as a response from an API (e.g., GPT-3) - #2 by Kenny
Although I may have misunderstood, but it seems as though streaming HTTP requests is currently not supported in Retool resources.
