Error while loading sharded meshes

Hello,

I have noticed an error in the web console that I can barely debug, for which I need a bit of help with.

Because we have a big data set, we have sharded (draco compressed) the data, in order to be fed to Neuroglancer. Some cell meshes still exceed a certain size and need to have a truncated requests/responses. I have noticed some of these meshes end up in an error in the console:

Their data is being fetched by Neuroglancer.
First request:

Second request:

But the mesh is not shown in the Viewer. I have tried to debug the chunk manager, but I had no luck. Also, the shard files seem to work, as I've loaded the problematic meshes with cloud-volume.

Do you have any idea where I could start debugging?

Best,
Andrei Mancu
