Attribute Error While Running Trame ParaView

[yangx789]

Hello, I'm trying to run a Trame app which references ParaView, but it shows AttributeError: 'Coroutine' object has no attribute 'on_message'. Any help will be appreciated

Here is more info of my venv:

• Anaconda venv
• Python 3.9
• ParaView 5.11.2
• Conda installed paraview (also 5.11.2), trame, trame-vtk, trame-vuetify

Conda recipe have some cross version dependencies issue.
You probably need to update trame, wslink, trame-server, trame-client or add more constraints on the various versions.

Try to be consistent between pip and conda.

Oh, you missed the most important part... You are using trame.tools.serve... Are you sure your app is designed to work with it?

[yangx789]

I'm running the exact same remote rendering app with Paraview as #531 which used tram.tools.serve

The issue "maybe" is that ParaView bring wslink<2 and your trame env is having wslink>=2.
Also I still don't know which code you are running and it is properly designed with a class encapsulation.

I changed to wslink<2 and that fixed the error. Thank you for your help.

Ok so for those coming here that means installing trame<3.6
