Exception raised on `/rhino/geometry/areamassproperties/compute-brep_bool_bool_bool_bool ` compute server

[highway900]

Hi,

We ran into this exception when using the compute server which was self hosted. Any ideas what might be causing it?

This is a script that will cause the issue.

import rhino3dm
import compute_rhino3d.Util
import compute_rhino3d.AreaMassProperties

compute_rhino3d.Util.apiKey = "1234"
compute_rhino3d.Util.url = "http://ip.com"
start = rhino3dm.Point3d(250, 250, 0)
end = rhino3dm.Point3d(0, 0, 0)
crv = rhino3dm.Curve.CreateControlPointCurve([start,end],1)
extru = rhino3dm.Extrusion.Create( crv, 500, False)
massProps = compute_rhino3d.AreaMassProperties.Compute6( extru, True, False, False, False )

Running this script causes the compute server to crash with this exception

That endpoint is expecting a Brep instead of an extrusion. You can change your code to pass a brep like the following

brep = extru.ToBrep(True)
massProps = compute_rhino3d.AreaMassProperties.Compute6( brep, True, False, False, False )

I'm not closing this issue yet as I would still like to fix the memory error occurring on compute
