JsonReaderException: not being able to see the response

[ZackStone]

Oracle's response is not a JSON, and I'm not able to see its content. There should be a better way to handle this case.

Error: Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value: <. Path '', line 0, position 0.
