GH - Missing Definition Objects in Rhino8 Server but not in Rhino8 app

Rhino Developer compute.rhino3d
1

I’ve seen these error messages before for missing components.

In this case, I can open the .gh file in the Rhino8 app running on the AWS server, while logged in as RhinoComputeUser. The file is in the RhinoComputeUser’s Document folder.

However, when I hit the Rhino server itself for the exact same .gh file served by my middleware server, I get the Missing Definition Objects error.

Is there another possible explanation for these messages besides missing components.

(I have a mix of .gha componets and PackageManager components.)

Here are the log entries if that helps:

I am experiencing the same problem:

When I login to the VM and start Rhino & GH there everything works as expected. However, as soon as I use the same definition as a Hops component, or try to use it through a browser app, I get the error “GH - Missing Definition Objects”.

Any tips anyone?
