Qlik Sense Natural Language API doesnt return any nebula charts expect bar chart

[vighnesh_gawad]

Hi Team,

 I am trying to create chatbot in qliksense mashup using this tutorial. https://qlik.dev/embed/gen-ai/create-chatbot-nl-api/.  this tutorial uses this endpoint {qliksenseurl}/api/v1/questions/actions/ask to generate response either text or nebula js chart to show in chatbot. (https://help.qlik.com/en-US/sense-developer/February2024/Subsystems/NLBrokerAPI/Content/methods-post...)

I was able to follow tutorial and able to create chatbot which return nebula bar chart as response when ask by user but when I try to customize it to add other chart. It doesnt work.

I even tried with POSTMAN and it gave same result. I was able to retrive nebula bar chart but not others.
