No causing exceptions

[ivanalikin]

Hi,
I have an error "#: only 1 subschema matches out of 2" but it's not possible to know what exactly caused the error since the getCausingExceptions() returns an empty list.

I'm having the same issue; I get the message "#: 2 schema violations found" but there are no causing exceptions.

Thanks guys for reporting it. You may send a PR with a bugfix in
CombinedSchema.java but I won't fix it on my own until the middle of June,
due to other activities.

I've just committed the bugfix, it will be released with 1.4.0

[Sudesh1989]

Hi, iam facing the above issue when I call getCausingExceptions() method in ValidationException class. The getCausingExceptions() method returns valid exception list for multiple schema violations, but it returns empty list for a single schema violation?

I am getting this even in 1.9.2 version.

@erosb
Same thing with the latest version 1.11.1 returns empty list for a single schema violation !!

@electronABS please post reproduction details (schema, instance json).

• Instance to validate with one violation (agentId required but not exist)
  `
  {
  "agentType" ; "testType" ,
  "reportJSON": {
  "certificates": [
  {"certB64": "testCertB64",
  "certFileExt": "testCertFileExt" ,

  "finishedAt" : "2019-11-13T20:22:39+00:00"
  }

• Validate java service

`
public static List jsonValidator(File JSONSchemaFile, JSONObject JSONToValidate)
throws FileNotFoundException {
List listOfViolations = new ArrayList<>();
log.debug("starting validate json object...");
try {
InputStream schemaStream = new FileInputStream(JSONSchemaFile);
JSONObject jsonSchema = new JSONObject(new JSONTokener(schemaStream));
Schema schema = SchemaLoader.load(jsonSchema);
schema.validate(JSONToValidate);
} catch (ValidationException e) {

listOfViolations = e.getCausingExceptions().stream().map(ValidationException::getMessage)
					.collect(Collectors.toList());
		
	}
	return listOfViolations;
}

`

• Expected behaviour
  listOfViolations : [#: required key [agentId] not found]

• Actual behaviour
  listOfViolations : []

Hi @electronABS I ran a test with your input and got the following output (by calling Validationexception#toJSON(), which looks correct for me (2 causing exceptions):

{
    "causingExceptions": [
        {
            "causingExceptions": [],
            "keyword": "required",
            "message": "required key [agentId] not found",
            "pointerToViolation": "#",
            "schemaLocation": "#"
        },
        {
            "causingExceptions": [],
            "keyword": "required",
            "message": "required key [reportType] not found",
            "pointerToViolation": "#",
            "schemaLocation": "#"
        }
    ],
    "message": "2 schema violations found",
    "pointerToViolation": "#",
    "schemaLocation": "#"
}
