Object reference not set to instance of Object

Getting this error when setting up an API Authentication Failed trigger.

Product: PowerShell Universal
Version: 3.6.4

Can you please check the log file?

You can access it in Settings \ General \ Diagnostics. It will have a better error message.

Error unprotecting the session cookie.
System.Security.Cryptography.CryptographicException: The key XXX was not fond in the key ring.

This is the docker image, I just pulled 3.7.3 I’m trying to setup a trigger to alert when key attempt fails.
