Hello @colin_mckibben,
I changed the cohortid to 001 to mask confidential data. It is a 3-digit number without quotes. I validated the json at DuckDuckGo and it does say that the json is valid. My guess is that the connector is considering the entire list of userids as one user when I used $[0] as the root path and userids.[*] in the response mapping for userid. I will take a look at the ccg logs to see if I can find something useful.
Thanks
