1 year ago Hello @szykov ,
Thanks for reaching out. The expected usage of the ConfigCat JS SDK is to use it as a singleton during your application lifetime and dispose it at the end the application: https://configcat.com/docs/sdk-reference/js/#4-dispose-the-configcat-client .
Usually the 0 code means that the browser cannot send the request towards our CDN and the request doesn't even leave the browser - usually because of local network issues.
If you could share us more details about your usage we could help you further:
- What kind of web app is this application?
- Which SDK version do you use?
- Which polling mode do you use with what kind of parameters?
- How and when do you initialize the configcatclient?
- How do you use the configcatclient (getValue calls, etc.)?
It would be awesome if you could turn on debug logging in the SDK (https://configcat.com/docs/sdk-reference/js/#setting-log-levels), and send the debug logs as well. Also, if you could reproduce the issue, please check the network tab to find more information why the http request could fail towards our CDN.
Cheers, Lali

Describe the bug
when user navigate between pages sometimes get this error:
Failed to download feature flags & settings from ConfigCat. 0 -should we destroy all configcat clients when the user refreshes the page/navigates from the page? for example on beforeunload event?
To reproduce
in theory you should reload the page in the moment when configcat updates flags
Expected behavior
no errors.
