Conveyor V4 for Rhino 7 vs. Conveyor V4 for Rhino 8

Hello,

I have a grasshopper script, that is using conveyor to create a revit family (imported mesh from civil 3D and want to create it in revit as a family in the first place).

My colleague, who has a Rhino 7 version and Conveyor v.4.1.7, can run the script on his computer.
I tried the same script for Rhino 8 and Conveyor v.4.2 and also updated the script for Rhino 8 and Conveyor v.5 and it always gives me the same error (1Mesh objects failed to import).

Weird thing is that when I opened the script for the first time (WITHOUT having conveyor’s licence) it showed me that I needed Version 4.2.0 of Conveyor (Conveyor 4.2).

For me, it doesn’t make sense that you can run the script with the Version 4.1.7 (Conveyor 4.0) when it said that I needed the Version 4.2.0.0.

Thanks to whoever has some time to help!
Have a nice day.
