[gaston.m]

I'm trying to execute an aggregsation query that works well in  mongoshell but produces errors in Jaspersoft Studio:

com.mongodb.util.JSONParseException: { runCommand: { aggregate : 'customers',                pipeline : [ { $match     : { countryCode: { $nin: ["ES"] }}},                             { $addFields : {
