Could you please confirm the Data Integration Service version? I've just tried on 57.0.1 and I cannot recreate the issue. Could you please check whether all the services under your Secure Agent are up and running? To do so please navigate to Administrator Service > Run Time Environments > click your Secure Agent.
Thanks for the reply. Data Integration service version is 57.0.3 and yes all the services are up under my secure agent but I am still facing the issue. I tried restarting the agent as well but didn't helped.
Did you try profiling with a different secure agent?
Also are you able to run DI mappings using this particular secure agent?
