Hi,
Hops 0.9.0 from the PackageManager currently doesn’t seem to work at all in Rhino 7 (7.13.21313.11002, 2021-11-09):
The Flask server runs fine in debugging mode.
I’ve installed all CPython dependencies in a virtualenv, like I pretty much always do:
And I’ve tested numerous, previously working scripts of mine and all produce the same error.
I’m currently using CPython 3.9.7.
Thanks for the question. I just tested Hops on the same build your running, and the example flask server seems to run fine on my machine. The only difference in my setup is that I’m running Python 3.10 and have the latest version of pip installed. Have you tried upgrading python to (3.10) and pip to (21.3.1) and then trying to reinstall flask and the ghhops_server?
Alternatively, you could downgrade Hops to the previous version (via the package manager) to see if it’s something in the new build that is broken.
If you downgrade to Hops 0.8.0, do things work?
I’ve installed Python 3.10.0 and upgraded pip to 21.3.1 and now rhino3dm fails to install inside the virtual environment.

We don’t have a 3.10 build of rhino3dm yet. Sorry about that.
LOL, I’ll try again with Python 3.9 tomorrow and a downgraded Hops. It’s late and I’m tired!
I created a new virtualenv with Python 3.9.7 and downgraded to Hops 0.8 and the same error as mentioned above persists:
1. Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Resthopper.IO.IoResponseSchema' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
Path '', line 1, position 1.
It’s seems to be an issue with the Hops component, because my CPython script that I ran with the Flask debugger active, didn’t display any errors during the process?
Btw, both ghhops_server and its rhino3dm dependency install fine in CPython 3.9.7.
Try setting your flask app debug mode on. I’m hoping this will show the json that is being returned to Hops so we can figure out what it is that hops is improperly trying to deserialize.
Oh, this is failing while trying to get the metadata that describes how a component should be laid out.
While all of this is running, open your browser and paste in the path that you are using for the component. We may be able to see what the json is there that is being returned
I mistook having a debugger active and setting app.debug=True as two different things. Sorry
I’ll try to repeat this on my Mac. Andy recently joined the company and is still in progress with getting set up with a Mac.
Thanks for looking into it.
Any news?
I updated my Mac to Monterey and am having issues just getting ghhops_server running. I think this is something wrong on my side, but this is taking longer to debug than I had hoped.
OK, thanks for update. I’m still on Big Sur though.
It looks like AirTunes was listening on port 5000. Switching to 5001 does work now. I do see the ghhops_server returning an array of one item which it shouldn’t be doing.
[edit] - I take that back, I’m not seeing the array being returned. I was looking at the incorrect endpoint
What is the path that you are entering for your component? I’ll try to use the exact same path
I didn’t enter a path! I entered a the server address: http://127.0.0.1:5000/
