SAP Buildapps: Configure SAP BTP destination REST API integration " status ok"307" error

I have created the app and the view was good and able to see it on the web. But when I am trying to configure API "SAP BTP destination REST API integration" It is throwing me an error message Status "ok" 307.

Not able to post data or retrieve the data.

I am working on SAP build apps sandbox (SAP).

what do I need to enter "DefinitionId" in the JSON file please advise.

ENCODE_JSON({ "definitionId": "<your definition ID>", "context": query.record })

Thanks,

Lakshmi.
