--------------------------------------
> NullPointerException, in case Locations are null in a GraphQL error response
> ----------------------------------------------------------------------------
>
> Key: SLING-9870
> URL: https://issues.apache.org/jira/browse/SLING-9870
> Project: Sling
> Issue Type: Bug
> Components: GraphQL
> Affects Versions: GraphQL Core 0.0.6
> Reporter: Jabran Asghar
> Assignee: Bertrand Delacretaz
> Priority: Minor
> Fix For: GraphQL Core 0.0.8
>
>
> *Problem*
> In case GraphQLError does not contain any Location information, rather when
> the list of locations will be null [0], then a NullPointerException is
> thrown. This causes a non-meaningful response to be sent back to client.
> For example, the following query will cause a NPE:
> {code:java}
> { article(_path: "/non-existent/path/to/an-article")
> {
> _path
> }
> }{code}
>
> *Proposed solution:*
> Should be a null check for {{error.getLocations().}}
> [0]
