Hi @Karin
From the information you’ve provided, it appears you are trying to receive data sent from a beta v3 connector (sketchup) in a v2 connector (blender).
Our v2 connectors are not forwards compatible with data sent from a v3 connector (or vice versa).
As such, I recommend you downgrade your Sketchup connector to version 2.21.1 (since we don’t currently have a v3 blender connector), and resend your data.
Please see this post Next-Gen Connectors: Supported Workflows and FAQ - #3 by jonathon for further explanation.
