nifi fetching attribute from json file

I need to fetch the second attribute from a json file. and have tried to use 'evaluateJsonPath' processor and/or 'attributetoJson' processor, in both of which case i always get the whole line instead of single attribute.

in the json processor I added the property as 'bouncers_mobile_social' and value as '$.bouncers_mobile_social' yet getting the full line.

the sample json is {"mtimespent_other": 0.4, "bouncers_mobile_social": 45, "numvisitors_mobile_search": 647}

Please suggest

I created a template demonstrating that a GenerateFlowFile processor which creates the JSON you provided and is passed to an EvaluateJSONPath processor with the property you provided works. Please check the configuration, typos, unexpected input data, etc.
