Bence, Images do not come through on most Apache lists ( I didn’t get it for sure ). What version of nifi, what version of the processors are you using? What is the name of the processor? We recently landed record based processors, but I am not sure there has been a release with them yet.

The format for OPCUA was a bit different. *So to approach this and allow these "special" characters ('=',';') on the variableAddress we proposed to use the following syntax: 'MaxCurrentImax'='ns=2;i=33'At the moment, we created a method "parseAddressString()" whose idea is to detect whether the protocol is OPCUA (or any other that could be included), to force the following variable address syntax: 'varName1'='varAddress1';'varName2'='varAddress2'* Hope this helps.
