@adhishankarit  The issues is being caused by the line returns used in the middle of the NiFi NiFiExpression Language (EL) ifElse() function you are using. The text box where you enter your NiFi EL uses a NiFi editor that highlights to show proper EL format.  You'll notice your EL stops highlighting once you reach first line return. So you'll notice character 32 is the first single quote character.  Since EL breaks at this point it fails to find the matching second expected single quote. This leaves you with two options: 1. Create flat json without the line returns. 2. Looking at result you are trying to achieve, design your NiFi EL differently: Note proper NiFi EL highlighting above. Hope this helps, Matt ...

@Lallagreta  Make sure you do not have any line returns in the values for your dynamic properties added in the UpdateAttribute processor.  When you click on the value field for each property you should not see a line "2". For example: Above would result in the value assigned to the FlowFile Attribute having a line return.  If this is the case, edit the properties value(s) to remove the line returns so you only see one line (1).
