When trying to receive my revit file in blender, I get a error report: 'Python: Traceback'

Hi,
I’m trying to receive my revit file in Blender using the Speckle add-on, but while doing this I get an error report: ‘Python: Traceback’.

It’s my first time trying out Blender and Speckle so everything is new for my on these applications.
First I followed this video to install the add-on: https://www.youtube.com/watch?v=tvSAaflRwOM
and after this I was following this video: https://www.youtube.com/watch?v=dPgqR_8BtZ4
So where it goes wrong is when I click on ‘receive’, I checked on the clean meshes, as said in the video, and clicked on ‘OK’. After this the box with the error report appaers. (see screenshot below)

So how do I solve this?

Kind regards,

edit:
in the meantime, a friend of mine who is familiar with blender, not with speckle, told me the error said there has to be something in the box of ‘Version’. Now I’ve compared this box in my window and the one of the video, there is something there, but I don’t know how to get this…

Looks like you’re tryjng to receive from an empty Speckle model, you don’t have a model version selected, and if there’s none in the drop down, it’s likely you haven’t sent anything yet?

You must first send a model to Speckle before you’re able to receive it.

If you still don’t see the model version in the list, try the refresh button next to projects selection.
You could also open your project in the web to double check you’re sending to the correct project.

Thank you for your reply,

I tried sending the model again. After sending it, I saw the model on the web interface and noticed the ID appeared in Blender in the ‘Version’ box. I clicked ‘OK,’ and it started loading. However, I accidentally closed the web interface tab during this process.

When I tried reopening the web interface, it kept loading for a while and eventually displayed an error.


In Blender it is still loading:

From your screenshots, you look to be sending quite a large model.

Are you able to send a smaller view from revit, and tey receiving that in blender, rather than sending/receiving everything from the revit model?

This would help determine if your problem is with all send/receives, or just large ones. Thank you.
