Issue with SpecklePy recomposing BRep objects?

On attempting to retrieve a BRep pushed from Grasshopper, via operations.receive(obj_id=id, remote_transport=transport), the following error occurs:

Traceback (most recent call last):

IndexError: list index out of range

I’m not sure why the i + 9 term occurs but it feels like a code smell?

BTW, this is successfully retrieved through the GH Receive component

Hi Daniel, sorry for the slow reply! I know @izzylys has pushed quite some updates recently so hopefully this is no longer an issue :slight_smile:

Hey @daniel-fink :wave:,

As mentioned by @teocomi, @izzylys pushed some updates on Brep support recently. I’ve tried to replicate your error on my end but I received the brep object successfully. Let us know if this is the case for you.

:round_pushpin: Don’t forget to update specklepy :snake: using pip install specklepy --upgrade
