We’re noticing that the ability to do JSON schema validation using using everit’s JSON validator referenced [here](http://forum.katalon.com/t/how-to-validate-the-json-response-with-expected-json-schema/14029/8) appears to have broken sometime after 5.9.0. Error message when running the same script in v6.0.4 on: ```auto org.codehaus.groovy.runtime.InvokerInvocationException: java.lang.NoSuchMethodError: org.json.JSONObject.toMap()Ljava/util/Map; at com.api.EveritValidator.invokeMethod(EveritValidator.groovy) at com.kms.katalon.core.main.CustomKeywordDelegatingMetaClass.invokeStaticMethod(CustomKeywordDelegatingMetaClass.java:49) at Crud_v3.11 - Retrieve campaign, validate JSON.run(Crud_v3.11 - Retrieve campaign, validate JSON:25) at com.kms.katalon.core.main.ScriptEngine.run(ScriptEngine.java:194) at com.kms.katalon.core.main.ScriptEngine.runScriptAsRawText(ScriptEngine.java:119) at com.kms.katalon.core.main.TestCaseExecutor.runScript(TestCaseExecutor.java:342) at com.kms.katalon.core.main.TestCaseExecutor.doExecute(TestCaseExecutor.java:333) at com.kms.katalon.core.main.TestCaseExecutor.processExecutionPhase(TestCaseExecutor.java:312) at com.kms.katalon.core.main.TestCaseExecutor.accessMainPhase(TestCaseExecutor.java:304) at com.kms.katalon.core.main.TestCaseExecutor.execute(TestCaseExecutor.java:238) at com.kms.katalon.core.main.TestCaseMain.runTestCase(TestCaseMain.java:114) at com.kms.katalon.core.main.TestCaseMain.runTestCase(TestCaseMain.java:105) at com.kms.katalon.core.main.TestCaseMain$runTestCase$0.call(Unknown Source) at TempTestCase1555593737838.run(TempTestCase1555593737838.groovy:21) Caused by: java.lang.NoSuchMethodError: org.json.JSONObject.toMap()Ljava/util/Map; at org.everit.json.schema.loader.SchemaLoader$SchemaLoaderBuilder.schemaJson(SchemaLoader.java:187) at org.everit.json.schema.loader.SchemaLoader.load(SchemaLoader.java:259) at org.everit.json.schema.loader.SchemaLoader.load(SchemaLoader.java:245) at org.everit.json.schema.loader.SchemaLoader$load.call(Unknown Source) at com.api.EveritValidator.verifyJsonSchema(EveritValidator.groovy:23) at com.api.EveritValidator.invokeMethod(EveritValidator.groovy) at com.kms.katalon.core.main.CustomKeywordDelegatingMetaClass.invokeStaticMethod(CustomKeywordDelegatingMetaClass.java:49) at Script1540201659864.run(Script1540201659864.groovy:25) ... 11 more ``` * * * Test Case: ```auto WS.comment("Validate response schema") responseJson = response.getResponseBodyContent() CustomKeywords.'com.api.EveritValidator.verifyJsonSchema'(responseJson, schema) ``` EveritValidator: ```auto class EveritValidator { /** * Send request and verify status code * @param stringJson Json to validate * @param stringSchema validation schema */ @Keyword def verifyJsonSchema(String stringJson, String stringSchema) { JSONObject rawSchema = new JSONObject(new JSONTokener(stringSchema)) Schema schema = SchemaLoader.load(rawSchema) try { schema.validate(new JSONObject(stringJson)) KeywordUtil.markPassed("Valid schema") } catch (ValidationException e) { StringBuffer outmessage = new StringBuffer() outmessage << e.getMessage() << "\n" e.getAllMessages().each { msg -> outmessage << "$msg \n" } KeywordUtil.markFailed(outmessage as String) } } } ``` Please advise. Again, when we run it on 5.9, no problems at all. Any versions later and it fails with the error listed above. Thanks! ---

Hey Morgan Not sure if this will help, I’m not familiar with this API set. In the linked discussion, @Ibus makes a point that you should use a JSON array object (and not a JSON object object): ![image](https://europe1.discourse-cdn.com/katalon/original/2X/a/a211941bd426d6859b7400eeec1bbbf7aff60754.png) ---

Hi Russ! I tried that when I was troubleshooting but it didn’t seem to make any difference. Thanks though! ---

In the linked discussion, the response is retuned as an Array and that’s why you need the JSONArray. This API will return a Json Object. The API response is kinda like this: { “Name”: “test”, “DateCreated”: “2019-04-10T12:36:51”, “StartDate”: “2019-04-12T21:00:00”, “EndDate”: “2019-04-13T20:59:00”, “LastUpdated”: “2019-04-15T12:45:32” } ---

@Morgan @Mihai_Augustin_Sarat i will look into it … i no longer have kata installed but will do it tomorrow if the time allows most probably with the new version some .jar’s are conflicting … ---

@Russ_Thomas is a different case now … but that reminds me that i promised to make a coherent tutorial on this matter … will do one day … perhaps i havr to re-write the keyword to make it aware of the response type and choose array or object … that will save some people from headache 🙂 ---

@Morgan can you please edit your post and re-format the log as /code mark-up to make it more readable? i think the forum plaform is js just using markdown, you have hints in the edit area and preview. pleaaase ---

I did some research, and, as I was afraid the issue is created by the **org.json** library being added into the Katalon since … I don’t know exactly what version. E.g, opening a sample project with Katalon 5.9.0 the following is generated into the project .classpath file (stripped content to the lines we are interested): ```auto ........... ........... ``` We have only **json-20180130.jar** grabbed by the everit.json as a dep and the test is running just fine. However, with 6.1.2 we may find as follows: ```auto ........... ........... ........... ``` Note that, in addition to the org.json lib we import into the project, we have also **org.json\_20140107.0.0.jar** , the one used by katalon himself, which is an older version. Unfortunately, Katalon is attempting to load that one … and not the one we need, therefore the error above. So … we may have to summon other jedi master’s to help us in solving it. @devalex88 @kazurayam any idea how can we convince katalon to compile/import at the TestCase runtime the right library from the project and not the one from Kata … and only for the keyword/testcase? Attemtping to replace the library in Katalon himself lead to crash, looking into logs looks like plenty of katalon libs depend on that one … ---

@Mihai_Augustin_Sarat you can try to use jackson untill this get fixed … altough i don’t remember what are the deps of it … from various logs posted here and there,i think jackson is already present in katalon. you will have to write a new keyword … but you can figure it out. i think it is still one wroted by me in one of the poc projects … see: [https://github.com/java-json-tools/json-schema-validator](https://github.com/java-json-tools/json-schema-validator) use the code samples to figure out how it works: [http://java-json-tools.github.io/json-schema-validator/2.2.x/index.html?com/github/fge/jsonschema/examples/package-summary.html](http://java-json-tools.github.io/json-schema-validator/2.2.x/index.html?com/github/fge/jsonschema/examples/package-summary.html) ---
