-------------------------------------
Summary: Hide Stack Trace and Details of Certain Server Errors
from Clients
Key: TINKERPOP-2866
URL: https://issues.apache.org/jira/browse/TINKERPOP-2866
Project: TinkerPop
Issue Type: Improvement
Components: server
Affects Versions: 3.5.5
Reporter: Cole Greer
The current behaviour of gremlin server when an error or exception is thrown is
to serialize the full throwable and return it to the client.
Based on
[this|https://lists.apache.org/thread/qb5o0vxk927n00csht4xdcfmw34qdhmd]
discussion in the dev list, it is preferable to only return errors which might
be considered useful to a user, and replace other errors with a more generic
InternalServerError response.
There remains an open question of exactly which errors and exceptions should be
returned in detail. Current intention is continue returning all `Exception`s
which are thrown. Any `Error` will be replaced with InternalServerError unless
the original error is included in a whitelist which allows it to be sent. If
any `Exception` is identified which the community feels should not be returned,
a blacklist of exceptions can be added as well.
