Couldn't find parent type for 'K2Node_GetSequenceBinding'

Hallo friends, I have used a code taken in Github for send mqtt command via Unreal, all work fine but if I try to package game I receive this error:

Error: Couldn’t find parent type for ‘K2Node_GetSequenceBinding’ named ‘UK2Node’ in current module or any other module parsed so far.

Someone write about this error in this manner: “I guess that’s because it is using editor only functions”

Someone have a solution to fix this problem?
