Hi @loginerror,
UiPath is able to process the request initially in the http request activity .
This is a scenario where , simple authorization access is used and only username field is used and password is left blank as per the clients model.
But later on when we run the request UiPath is unable to process the request successfully.Ui path throws bad 401 error of Unauthorized.
I had provided an alternative solution to one of the users in the above thread
