-------------------------------------------
Summary: Improve error reporting in GraphQL output
Key: SLING-10422
URL: https://issues.apache.org/jira/browse/SLING-10422
Project: Sling
Issue Type: Improvement
Components: GraphQL
Affects Versions: GraphQL Core 0.0.10
Reporter: Bertrand Delacretaz
The error reporting features of the GraphQL Core can be improved, as in this
example (from [http://spec.graphql.org/June2018/#example-08b62)] where an
{{extensions}} key is used to provide details on specific errors:
{code}
{
"errors": [
{
"message": "Name for character with ID 1002 could not be fetched.",
"locations": [ { "line": 6, "column": 7 } ],
"path": [ "hero", "heroFriends", 1, "name" ],
"extensions": {
"code": "CAN_NOT_FETCH_BY_ID",
"timestamp": "Fri Feb 9 14:33:09 UTC 2018"
}
}
]
}
{code}
We might for example create an interface for Exceptions that provide
information for such {{extensions}}, maybe a Map that can be used to add
free-form information there. And probably define some standard key names and
formats inside the {{extensions}} for machine consumption.
