Not able to set connection between Oracle Integration Cloud and the UiPath Orchestrator

Hi,
I try to connect Oracle Integration Cloud to the UiPath Orchestrator using the UiPath RPA adapter. But every-time I try to set the connection and security parameters I always have this error “Unable to test connection “SAM_ORACLE_CONN”. [Cause: CASDK-0005] : A connector specific exception was raised by the application”
Thanks for helping me!
