Getting undefined error with react-meteor-data

After upgrading to Meteor 1.5.1, I’m getting the following error.

Hi - I had this same problem, here’s how I solved it.

Read this for some background: https://github.com/meteor/react-packages/issues/225

Then go to your website home directory and update the React NPM packages like this:

1st do “meteor npm outdated” to identify the outdated React packages.

Then 2nd do one or probably several commands like “meteor npm update --save react-rest-of-package-name”

Then start up meteor and this error should be gone - it is gone for me at least. Presto!
