1. Create a connect-service (GET) which takes multiple values in same parameters of the query string (kind of array)
2. Run the metadata and connector wizard with the service URL
3. try to call the service by passing the required values .
We tried to manually format the query string parameter by appending "&consumer_ids=" and pass to the service URL .
But Pega internally does the URL encoding and converts the special chars like "&" and "=" due to which the service fails
