loopback 2 - defining an array of objects on a model

if I have a usermodel and I define:

"events": {
  "type": [
    "Object"
  ]
},

Do I need to define anything else in the usermodel.js to be able to post things like: [{name: 'sample', ...}, ...] to the user table's events column?

I ask because if I remove this particular definition from the .json the app compiles and the database migrates, but with it in, the app compiles but the database states there was an issue with the users findByid. My debugging has narrowed it down to this particular set of code.
