Failure on publishing with masks enabled

[jil24]

Publishing when I have masks loaded results in this error:

Publishing after removing the masks works fine.

If I change app.py line 1239 from
'opacity': c['opacity']
to
'opacity': 1
Then it publishes correctly, with fully opaque masks. Is this maybe a partly implemented opacity control?

I am also experiencing the same issue and confirm that the fix @jil24 mentions allows publishing (with the set opacity). @jmuhlich is a fix planned for this issue?

Hi @jil24 @adamjtaylor I have resolved this issue in v1.11.3. It turns out v1.11.2 had the latest version of the python server, incompatible with an outdated version of the javascript browser. The master branch has the updated solution, with a patched v1.11.3 executable soon to follow.
