Error while testing the Bot in other system

Hi all,

We are getting an error message like this while loading the bot in studio. It was developed and testing in one m/c during development everything went well but while loading the bot in other system in production testing we get this message.

Can any one let me know why this happens.?
Thanks in advance.

Hi ,

Try taking backup of project.json ,remove it from project folder and open Main.xaml that should download the packages properly
