Stuck at Getting Survey Details from SurveyMonkey

[georgio_hb]

I'm trying to connect to the Survey Monkey API via a hard corded connection (set in a variable) but the connection is giving me such error: QVX_UNEXPECTED_END_OF_DATA: HTTP protocol error 400 (Bad Request): {"error": {"docs": "https://developer.surveymonkey.com/api/v3/#error-codes", "message": "Invalid URL parameters.", "id": "1003", "name": "Bad Request", "http_status_code": 400}}

Although, if i try the same but while getting surveys bulk, it works

vID is equal to a survey id

Table:
SQL SELECT

....
WITH CONNECTION(Url "$(vURL2)");

let vURL2 = 'https://api.surveymonkey.com/v3/surveys/$(vID)/details';

vID is a Survey ID
