---------------------------------
Resolution: Fixed
> Add stackTrace to Bulletin
> --------------------------
>
> Key: NIP-10
> URL: https://issues.apache.org/jira/browse/NIP-10
> Project: NiFi Improvement Proposal
> Issue Type: Improvement
> Reporter: Pierre Villard
> Assignee: Pierre Villard
> Priority: Major
>
> As a NiFi user, it is not always easy to quickly access the logs. Bulletins
> are a good way to surface potential errors when data is being processed in
> the flow but in case this requires deeper debugging, the information
> currently provided in a bulletin is not always enough.
> In such a case the NiFi user may not have permissions or easy access to the
> logs of the NiFi instance and would need to get in touch with a NiFi admin
> able to retrieve the underlying log message for the bulletin and provide the
> full stack trace. This can make the overall troubleshooting process longer.
> It could be useful to add a stackTrace String to the Bulletin object in
> nifi-api and provide the option to expand a bulletin in the Bulletin Board
> view in order to see and easy copy in the clipboard the potential stack trace
> associated to the bulletin.
> We want to use a String instead of a Throwable to make sure we do not have
> serialisation issues across the NiFi nodes but we want to make we retain the
> proper format of the stacktrace for proper rendering in the UI.
> Additionally, it may be good to evaluate if we should specifically remove the
> value of this new field when being called via APIs that are not for the
> bulletin board. This may not be necessary though as we never retrieve a large
> number of bulletins anyway.
> Expected changes:
> * The API change would be to add a stackTrace String field to the Bulletin
> object in nifi-api
> * In the implementations of LogObserver, convert the throwable into the
> string representing the stack trace and add it to the bulletin
> * In the UI, improve the bulletin board to properly render the stack trace
