Error mapping incoming response to < Property Name >: org.codehaus.jackson.JsonParseException


While calling Connect-REST via Data Page in Service-File rule activity. I am getting following error :

 ** Error mapping incoming response to <Property Name>: org.codehaus.jackson.JsonParseException: Unexpected character ('T' (code 84)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
 at [Source:; line: 1, column: 2] ( Screenshot attached)

When I tried manually running Data Page to call Connect-REST, it is working fine. I am getting OK Response.

But when same Data page is referred from activity in Service-File rule i get an error.

High Level Requirement : Use rows in CSV file as parameter for REST api call. So i am parsing CSV file via Service-File and then in parsing Activity of Service-File, i am calling Data-Page passing the parameters.

Screen Shot of rules attached.
