Karate: After updating from 0.9.2 to 0.9.5 getting the error “java.lang.IllegalArgumentException: Illegal group reference”

Created on 20 Mar 2020 · 7Comments · Source: intuit/karate

The issue is with generating Timeline.html file, Specifically in the code
html = html.replaceFirst("//timeline//", sb.toString());
which is in Engine.java(L500)

When Scenario name has any special characters in it, we are getting this error.

java.lang.IllegalArgumentException: Illegal group reference at java.base/java.util.regex.Matcher.appendExpandedReplacement(Matcher.java:1068) at java.base/java.util.regex.Matcher.appendReplacement(Matcher.java:998) at java.base/java.util.regex.Matcher.replaceFirst(Matcher.java:1408) at java.base/java.lang.String.replaceFirst(String.java:2081) at com.intuit.karate.core.Engine.saveTimelineHtml(Engine.java:500) at com.intuit.karate.Runner.parallel(Runner.java:357) at com.intuit.karate.Runner$Builder.parallel(Runner.java:181) at com.pro.api.tests.features.TestRunner.testAllFeatures(TestRunner.java:56) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.apache.maven.surefire.junit4.JUnit4Provider.execute(JUnit4Provider.java:365) at org.apache.maven.surefire.junit4.JUnit4Provider.executeWithRerun(JUnit4Provider.java:273) at org.apache.maven.surefire.junit4.JUnit4Provider.executeTestSet(JUnit4Provider.java:238) at org.apache.maven.surefire.junit4.JUnit4Provider.invoke(JUnit4Provider.java:159) at org.apache.maven.surefire.booter.ForkedBooter.invokeProviderInSameClassLoader(ForkedBooter.java:384) at org.apache.maven.surefire.booter.ForkedBooter.runSuitesInProcess(ForkedBooter.java:345) at org.apache.maven.surefire.booter.ForkedBooter.execute(ForkedBooter.java:126) at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:418) [ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1,181.97 s <<< FAILURE! - in com.pro.api.tests.features.TestRunner [ERROR] testAllFeatures(com.pro.api.tests.features.TestRunner) Time elapsed: 1,181.905 s <<< ERROR! java.lang.NullPointerException at com.pro.api.tests.features.TestRunner.testAllFeatures(TestRunner.java:61)

@vini46 @apparnaa-v this will be fixed in the next version and there should be a 0.9.6.RC1 released by monday. in future do follow twitter or something and help us try out new versions to avoid these surprises

sorry you have to follow the process, and read it fully because most people solve the problem on their own when they do it, no one else has reported what you have - so is is most likely something you missed, or not related to karate - there is only one way to find out https://github.com/intuit/karate/wiki/How-to-Submit-an-Issue

This issue is explained with basic examples below - The exact same code is passing in version 0.9.4 but failing in 0.9.5.

Could you verify that this is not a version related issue?
