In previous version i could install rocketchat apps in “offline mode” by downloading the zip file and enabling apps + developer mode and uploading the respective zip.
this seems to not work anymore these days (3.10.5)? after uploading the zip file (poll.rc-app.zip) it says "Invalid App Package. Could not find the classFile (PollApp.js) file. Did anything change? on an older Install, where this app has been installed last year, the app still works fine.
does anybody happen to know a workaround?
