Comment 2 for bug 2050075

Thank you for the fix in Calibre 7.5.1.

It works well in offline mode. Yeah.

But when I reconnect to the server after the app (fully kiosk browser, chrome) is swiped off, the following error appears, even when the server is online

Uncaught TypeError: Cannot read properties of undefined (reading 'is_local')
Error at http://yyz.xmm/:10879:141

It can be closed and the reading is normal, until the next clean connection
