I’m working on re-creating a SmartForms application for a client — which was already in progress when I took over for another engineer — when I bumped into the exception described in the the title. This application was deployed from another environment.
Where’s the problem?
This was a really weird one. A client’s application suddenly suffered from this error in all environments simultaneously. The root cause had nothing at all to do with K2 blackpearl, but it affected the service keys of the instance of a service, which brought down the service and caused the exception.
