I am using PX4 as my flight stack and getting the errors below whenever I launch the PX4.launch
[ERROR] [1565784217.763478228]: ODOM: Ex: Could not find a connection between ‘local_origin_ned’ and ‘fcu’ because they are not part of the same tree.Tf has two or more unconnected trees.

I have PX4 flow sensor and want to do some image processing indoor flight so no GPS is applicable. Could you please guide me through this?
