[mistral] cron triggers execution fails on identity:validate_token with non-admin users


Hi!

Are you aware of other issues with cron triggers and trusts? Iâ??d like to reconcile all of that somehow. The users who I personally work with donâ??t use cron triggers so I donâ??t have that much practical experience with them.

Thanks
