@Tra ,   This is a problem with your version of Java, which is very old. You must either upgrade Java to the Java 11 (or at least to the latest Java 😎 or install the JCE extension for your current JDK.   Please see details in here: https://community.cloudera.com/t5/Support-Questions/Nifi-starts-without-error-but-cannot-connect/m-p/338254/highlight/true#M232781   Cheers, André   ...

@J0sh ,   If you use a ReplaceText with the following settings it will clean up the garbage in your flowfiles: Search Value: (?s)(^|(\})<br>).*?(\n).*?(<br>(\{)|$) Replacement Value: $2$3$5   This file, though, has not 1 JSON, but 8 different JSON fragments. So the resulting flowfile will still have 8 lines, each with a valid JSON. You must use a SplitText process to separate those into 8 different flowfiles before applying the EvaluateJSONPath.   Cheers, André   ... View more

@sahil0915 ,   Please try the JoltTransformJSON processor with the following Chain specification: [ { "operation": "default", "spec": { "json_data": { "items[]": { "*": { "quality": "good" } } } } } ]   Cheers, André   ... View more

@r_rachuri ,   Your expression works for me on NiFi 1.15.2. It's too complicated, though, and it still leaves a pair of curly brackets behind.   Try using this one instead: \{[ \n]*\}[ \n]*,?[ \n]*   Cheers, André     ... View more
