I'm trying to use expression languge to generate ISO string in Nifi getMongo Query field using following query, { "remindmeDate": { "$gte": "${now():format("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'",'GMT')}", "$lte": "${now():toNumber():plus(359999):format("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'",'GMT')}" } } But i'm getting invalid JSON error error as double quotes are not escaped. When we try to escape it using \ operator, nifi is not evaluating the expression language. Is there any method or workaround to get this working ? Thanks in advance ... View more
