When trying to upload a file bigger than 1MB (not only, see flow below) I always get the famous "Connection lost" message.
Although this issue has been discussed numerous times before, it might be possible to address it, until it can be resolved (WebSocket 3.0?):
Why not rename the "Connection lost" message instead, to something like "Please wait" or "Loading"?
Most likely it will eventually return the desired output as the web-socket is being automatically replaced with a new one. Couldn't find this system message in
settings.js to rename.
My flow (try upload files bigger than 1MB):
upload.json (292.6 KB)
