Swetha commented on OLINGO-1374:
--------------------------------
I am also facing this issue.
Is there any workaround to fix this issue?
> Include "target" in error response caused by exceptions

> Key: OLINGO-1374
> URL: https://issues.apache.org/jira/browse/OLINGO-1374
> Project: Olingo
> Issue Type: Improvement
> Components: odata4-server
> Affects Versions: (Java) V4 4.6.0
> Reporter: Tobias Niehues
> Priority: Major
>
> Error responses should include error codes and target to enable user
> interfaces to tie validation errors to the related interface element.
> For example: The xml and json implementations of ODataDeserializer throw
> DeserializerExceptions and include the offending property in the error
> message. However, this information does not get propagated to the error
> handler.
>
> See:
> [https://github.com/apache/olingo-odata4/blob/master/lib/server-core/src/main/java/org/apache/olingo/server/core/ODataHandlerImpl.java#L81-L125]
>
> DeserializerException is converted to ODataServerError, but it is not setting
> the ODataServerError.target attribute. This results in error messages like:
> {{{"error":\{"code":null,"message":"Property: Type must not be null."}}}}
> I would expect the error message to look like this:
> {{{"error":\{"code": "INVALID_NULL_PROPERTY","message":"Property: Type must
> not be null.", target: "Type"}}}}
>
> As it is, I find it hard to customize error handling/validation as it is now.
> There is no nice way to replace ODataExceptionHelper, for example.
