[2.3.7] Execution exception[[NullPointerException: null]] in Production

[Roberto Castanedo]

Hi,

i´m getting a NullPointerException in production.

It happens kind of randomly, not on every request to affected URL, and it is quite hard to reproduce.

All the information I have is this weird stack trace, which tells me nothing.

Any ideas? What might I be doing wrong?

[ERROR] - from play in play-akka.actor.default-dispatcher-55 

Cannot invoke the action, eventually got an error: java.lang.NullPointerException

[ERROR] - from application in play-akka.actor.default-dispatcher-55 

! @6p8812jff - Internal server error, for (GET) [.. URL ..] ->
