Android mobile client failing with net::ERR_FILE_NOT_FOUND(file:///index.html)

After I did the bench update yesterday, I am not able to use the mobile client. I tried re-installing the app, which didn’t help. Tried ‘bench update’ again today, but still have the same issue. Any idea how to resolve this?

Check logs/frappe.log for exception.

Thanks @saurabh6790. I am getting the following exception

I don’t know what changed, but the last ‘bench update’ resolved the issue.
