Unexpected token on spread operator after update to ember-cli 2.14

[acgrama]

Not sure if I'm doing it right, but didn't solve my issue. I've added the transform-object-rest-spread plugin as suggested by the readme:

  const app = new EmberApp(defaults, {
    babel: {
      plugins: ['transform-object-rest-spread'],
    },
  });

Now I am getting this error:

The Broccoli Plugin: [BroccoliMergeTrees: TreeMerger (appTestTrees)] failed with:

From the few results I can google, this seems to be some version incompatibility issue, but I can't get any clear results.
Do you need any other information from me, like installed versions, etc.?

@telmaantunes Thanks a lot. Was facing this issue for one whole day 🗡

[rwjblue]

The README of ember-cli-babel specifically describes how to add the rest/spread support with ember-cli-babel@6. Please take a look over there, and let me know if that doesn't resolve the issue.

I'm going to close this issue (we can open a more specific one in ember-cli-babel repo if needed).

[telmaantunes]

solution?

[acgrama]

@telmaantunes The only solution was to postpone upgrading.... :-(
Maybe there is a way to solve it, but back then I didn't have a week to spend for fixing whatever compatibility bug this was.

[telmaantunes]

I found a solution. If you're using ember-cli < 2.13 write "babel6" instead of "babel".

babel6: {
      plugins: ['transform-object-rest-spread'],
},
