UnrecognizedPropertyException when reading an errors response.

[NicolaIsotta]

Response I'm using to test: {"jsonapi":{"version":"1.0"},"errors":[{"status":404,"title":"An error"}]} When reading this response with a ResourceConverter, an exception is generated:

java.lang.RuntimeException: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "jsonapi" (class com.github.jasminb.jsonapi.models.errors.Errors), not marked as ignorable (one known property: "errors"])

You should be able to instantiate converter instance using configured object mapper which will ignore unknown properties if needed.

[NicolaIsotta]

Yes, configuring an ObjectMapper avoids the exception. I would handle the jsonapi object natively in the lib since it's is in the specification, but that's just my 2 cents.

I just use ErrorUtils.parseErrorResponse, but it seems that function fails somehow: at com.github.jasminb.jsonapi.ErrorUtils.parseErrorResponse(ErrorUtils.java:33). I don't think this error should be responsibility of the user.

[jasminb]

@ben221199 you are right, I will publish a release that adds support for JSON API doc object as part of both error and regular resource response.

Fixed in #263
