Hi
We are experiencing getting no stacktrace on nullpointerexception in a Spring controller. We have no idea why? And no idea where to look?
Any help will be appreciated

Hi !
Can you elaborate on your issue ?
- do you have a NPE exception thrown in your app and you want to have the agent to capture it
- does your app with the agent throws NPE when the agent is added
- does the agent reports an NPE in its logs but there is no visible effect on the application ?
The transaction fails, and APM captures the exception. But it is only the first line, ending with "\n" of the stacktrace. So the stacktrace field is in the APM document.
can you provide a copy of the document stored in ES and the original exception stack trace if you have it ?
Also, can you provide your agent version and configuration ?
This is our log line on local output. We are using ver. 1.51.

The stack trace is in the log line you provided (the NPE is from d.d.t.d.domain.common.gateway.person.PersonIntern.<init>(PersonIntern.java:14))
Yes, but APM doesn't capture the stacktrace. We want to know why.
That log line is showing the stack trace in the error.stack_trace field, where are you expecting to see it?
