Get 500 error code for user during its first deployment

[mtangaro]

The first deployment of a new user gave me this error:

2018-11-24 17:44:15 DEBUG pool-7-thread-82 ToscaIDCInterface:730 - Orchestrator result: {“code”:500,“title”:“Internal Server Error”,“message”:“JTA transaction unexpectedly rolled back (maybe due to a timeout); nested exception is bitronix.tm.internal.BitronixRollbackException: RuntimeException thrown during beforeCompletion cycle caused transaction rollback”}

The others went fine. I've used the FutureGateway portal for this deployment.
