fixedpoint-sum demo isn't working

[JKOKAY]

When I try to connect, while the server is running, the Sum-Button stays disabled.
After checking the Webconsole it tells me "sodium_" is null, which looks okay, as opt.sodium is set to false.
Here is the complete error message from the console:
Uncaught TypeError: jiffClient.sodium_ is null
connect jiff-client.js:449
connect mpc.js:30
connect client.js:41
onclick client.html:1

I cannot replicate this error myself. The demo is working fine on my machine as is and also when I enable sodium.

What browser / version are you using? Can you run npm run-script test-demo -- demos/fixedpoint-sum/ from the root directory of JIFF?

I tried Chrome (version 101.0.4951.67) and Firefox (version 100.0) both running on Windows 10.
Chrome error :

Firefox error:

If I try to remove the line opt.sodium = false, I receive new errors:
Chrome:

Firefox:

It seems like I am missing something here, at least with the browser approch, as the script you mentionend (npm run-script test-demo -- demos/fixedpoint-sum/ ) is running fine (at least the log is very long and the terminal tells me the test passed).
