CHANNEL_ERROR: Issues Subscribing to Realtime Changes with Supabase
Some of my users are intermittently facing a CHANNEL_ERROR when subscribing to realtime changes. And I’m hoping for some guidance.
And occasionally, the associated fetch request to retrieve data also sometimes fails
Here’s the relevant code snippet for context:
When the CHANNEL_ERROR status occurs, I attempt to handle it with a handleReconnect function, which:
1. Removes the current channel.
2. Reinitializes the subscription.
3. Refetches data.
Additional Context, the users are accessing this functionality through a webview, where the app remains open for long periods. And In many cases, users place the webview in the background for extended durations before returning to it.
I also tried adding an 'online' and 'visibilitychange' eventlisteners but issue persists
1. Are there best practices for handling CHANNEL_ERROR in a more robust way?
2. Is there a way to debug or get more information about the cause of the CHANNEL_ERROR?
3. Are there specific configurations for the supabase.channel setup that could help prevent this issue?
