question javax.script.ScriptException: NameError: name 's' is not defined in in Support Questions https://community.cloudera.com/t5/Support-Questions/javax-script-ScriptException-NameError-name-s-is-not-defined/m-p/226767#M188627 <P>I want to check if a product ID exists in a file. I came up with following python script:</P><PRE>#!/usr/bin/python import os import java.io flowFile = session.get() exists = False if (flowFile != None): if !os.path.exists('/home/nifi/products.csv'): session.transfer(flowFile, REL_SUCCESS) else: asin = flowFile.getAttribute('asin') with open('/home/nifi/products.csv') as csv: if asin in csv.read(): exists = True session.transfer(flowFile, REL_FAILURE) if !exists: session.transfer(flowFile, REL_SUCCESS) </PRE><P>However I am getting an error which I find really hard to interpret. It basically just says javax.script.ScriptException: NameError: name 's' is not defined in <script> at line number 9 Any ideas whats causing this?</P><PRE>2018-11-05 19:27:29,267 ERROR [Timer-Driven Process Thread-2] o.a.nifi.processors.script.ExecuteScript ExecuteScript[id=e52f46d5-0166-1000-fc42-8e9565527c21] Failed to process session due to org.apache.nifi.processor.exception.ProcessException: javax.script.ScriptException: NameError: name 's' is not defined in <script> at line number 9: org.apache.nifi.processor.exception.ProcessException: javax.script.ScriptException: NameError: name 's' is not defined in <script> at line number 9 org.apache.nifi.processor.exception.ProcessException: javax.script.ScriptException: NameError: name 's' is not defined in <script> at line number 9 at org.apache.nifi.processors.script.ExecuteScript.onTrigger(ExecuteScript.java:239) at org.apache.nifi.controller.StandardProcessorNode.onTrigger(StandardProcessorNode.java:1165) at org.apache.nifi.controller.tasks.ConnectableTask.invoke(ConnectableTask.java:203) at org.apache.nifi.controller.scheduling.TimerDrivenSchedulingAgent$1.run(TimerDrivenSchedulingAgent.java:117) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: javax.script.ScriptException: NameError: name 's' is not defined in <script> at line number 9 at org.python.jsr223.PyScriptEngine.scriptException(PyScriptEngine.java:222) at org.python.jsr223.PyScriptEngine.eval(PyScriptEngine.java:59) at org.python.jsr223.PyScriptEngine.eval(PyScriptEngine.java:31) at javax.script.AbstractScriptEngine.eval(AbstractScriptEngine.java:264) at org.apache.nifi.script.impl.JythonScriptEngineConfigurator.eval(JythonScriptEngineConfigurator.java:59) at org.apache.nifi.processors.script.ExecuteScript.onTrigger(ExecuteScript.java:229) ... 10 common frames omitted Caused by: org.python.core.PyException: null at org.python.core.Py.NameError(Py.java:290) at org.python.core.PyFrame.getname(PyFrame.java:257) at org.python.pycode._pyx189507.f$0(<script>:18) at org.python.pycode._pyx189507.call_function(<script>) at org.python.core.PyTableCode.call(PyTableCode.java:171) at org.python.core.PyCode.call(PyCode.java:18) at org.python.core.Py.runCode(Py.java:1614) at org.python.core.__builtin__.eval(__builtin__.java:497) at org.python.core.__builtin__.eval(__builtin__.java:501) at org.python.util.PythonInterpreter.eval(PythonInterpreter.java:259) at org.python.jsr223.PyScriptEngine.eval(PyScriptEngine.java:57) ... 14 common frames omitted </PRE><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="93522-bildschirmfoto-2018-11-05-um-204321.jpg" style="width: 511px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/15338i6F1C244CEEA9D79C/image-size/medium?v=v2&px=400" role="button" title="93522-bildschirmfoto-2018-11-05-um-204321.jpg" alt="93522-bildschirmfoto-2018-11-05-um-204321.jpg" /></span></P> Sun, 18 Aug 2019 01:24:46 GMT artworkad 2019-08-18T01:24:46Z
