Weird issue where segmentation size isn't returning value

[umayaml]

This on our hemibrain production server:
This api endpoint for labelmap should return a voxel size but it returns empty:
http://emdata4.int.janelia.org:8900/api/node/52a13328874c4bb7b15dc4280da26576/segmentation/size/5901204314

But if I take a synapse point located on the body and search by x,y,z location it returns the label 5901204314:
http://emdata4.int.janelia.org:8900/api/node/52a13328874c4bb7b15dc4280da26576/segmentation/label/13945_18181_14767

So it seems like the body 5901204314 exists but not returning voxel size?
