ORA-39097: Data Pump job encountered unexpected error -12801 while expdp

ORA-39097: Data Pump job encountered unexpected error -12801 
ORA-39065: unexpected master process exception in MAIN 
ORA-12801: error signaled in parallel query server P..., instance <instance_name> 
ORA-01460: unimplemented or unreasonable conversion requested Job <job_name> stopped due to fatal error at <failure_time>. 


The problem seems to be a bug and the solution can be an update to minimum 11.2.0.4 version.
For me, the workaround was:

> alter system set  PARALLEL_FORCE_LOCAL=TRUE;
