TypeError: Object of type ProcessingState is not JSON serializable

Hi,

I installed the GUI according to the instructions. It does run the webserver part, and I am able to retrieve the configuration from the running CamillaDSP instance and visualise the filters and pipeline. However the GUI says " State: backend offline" and I get the following error:

Error handling request

TypeError: Object of type ProcessingState is not JSON serializable

I'm running CamillaDSP 0.5.2 and gui-backend 0.7.1.

Might the reason be that I'm running Python 3.7 instead of 3.6?

Hi! It looks like you are running the latest version of pycamilladsp. I'm working on updating the gui and backend for that, but I'll need a few days more on that.

The current version of the gui works with camilladsp 0.5.2, pycamilladsp 0.5.1 and pycamilladsp-plot 0.5.3. Can you try with those versions?

I also tried it myself with camilladsp 0.5.2... but downgrading pycamilladsp did the trick. Forget about that one. Thanks.
