What is the format of the (IDs to Follow) field in the Nifi GetTwitter processor ?

[#1]

Tried both using the Twitter username and @username notation but Nifi errors out with "invalid because Must be comma separated list of user IDs"

[#2 · Accepted solution]

I think this would be the numeric twitter identification number given to each user

That was it. Thanks ! Used http://tweeterid.com/ to convert from username to user id.
