I updated my project to 1.7.0.3 and it ran just fine from the project directory.
However, when I pushed it to production, with a metor build, I got the error in the client browser
“Uncaught Error: Cannot find module ‘core-js/modules/es6.object.is’”
This has only been reported before a few times in previous versions, so I looked in node_modules and there was no core-js, so I did a “meteor npm install core-js” and a redeploy and that fixed it.
My question is, was that the right thing to do? My understanding was that babel-runtime took care of core-js?
