findNearestNeighbors is a method of pointCloud objects. You must pass a pointCloud object into it as the first input argument. Both the documentation pages for the method in UAV Toolbox and in Computer Vision Toolbox state that the first input is a "Point cloud, specified as a pointCloud object."

Are you trying to call this method with a pointCloud as the first input or with something else as the first input? I suspect the latter.
