Qlik Sense Hub error: hub-chat-ui.js Uncaught Error: Automatic publicPath is not supported in this browser

[alessiodimatteo]

Hi everyone, after the upgrade to August 2023 I receive this error everytime I try to connect to the hub via DNS:

Uncaught Error: Automatic publicPath is not supported in this browser on the object hub-chat-ui.js. 

If I try to access the Hub with https://machineFQDN/vp, everything is ok and the error does not appear. The problem is when I try to reach the Hub with https://DNSname/vp , it does not work and I receive a white page. The virtual proxy definitely works also because https://DNSname/qmc works well.

It seems to be related to some packages of the Hub, can someone help?

Thanks.

Hi

I don't know if this Qlik Sense version use Webpack 5 or not. But in this module, you can find a plugin min-css-extract, and it's know to have issue wich can triigger your error. 
Then, you might at least patch your Qlik Sense site, or upgrade it to a more recent version. Maybe it'll solve the issue

Kind regards

Hi, 

I've a more detailed explantation to provide : The Bot module uses Webpack5, but some system like Cloudflare use Webpack4 by default. So it thrown the error. 

Solution is to investigate your proxy configuration, and check if something force use webpack4 and then change to webpack5

Kind regards

Hi @alessiodimatteo , @mpc 

Perhaps you found the root cause in the meantime; could you eventually share it? 

Based on the description ; what is the difference between machineFQDN and DNSname ? 

Do you have in the Virtual Proxy - Host Allow List  the DNSname ?
