Forums › 💬 NodeCanvas › ⚙️ Support › A required BBParameter field value for Task 'X' is not set!
hatchling.
hatchlingI keep getting this error and I don’t know what to do about it or why it happens. All of the required fields appear to be set, but some internal “BBParameter” is not being assigned.
The bizzare thing is the script appears to actually set the IK, though it does so while throwing a ton of NullReferenceExceptions and complaining that it cannot covert a GameObject to a BBParameter or something.

hatchlingNever mind, I found out that another object had a FSM without the correct variables attached. My bad, no error on your part.
GavalakisThanks for letting me know 🙂
