I don't believe this issue is related to PI Coresight. The PI Identity connected doesn't have read access to the trust table. Please check the mapping / trust you are using.
If you need further assistance on this issue, please consider opening a call at OSIsoft TechSupport.
It was working before and now it does not. Where is the trust table? I can't check the mapping/trust since that is where I get this error.
I can try the TechSupport.
Got it back. It was the user I was connected as got switched to the demo account so not read access. Switched to the admin user and now it is fine.
Thanks for your help.
