Cannot read property 'get' of undefined

Client was having an issue where only one of the content items wasn't loading within the CMS, all the others of the same content type were rendering up fine.

Unfortunately he already deleted it and recreated it (I was going to leave it so you guys could take a look), but I managed to grab a screenshot of the console before he did... If this is unhelpful to nailing down what happened, go ahead and close the issue.

Getting the same error on my website (ronikdesign). The Swig templates render fine and load all the content I had previously entered in the CMS, and I can also edit the template, but I can't edit the content itself anymore.

I got the same 'Uncaught TypeError' error today. You can see in my grid field, "events" the offending null value. I haven't talked to the client yet, but I imagine they deleted a row in the grid.

One value was also null in my case. I fixed it by POSTing to the API endpoint (http://www.webhook.com/docs/api-endpoints/#update_an_item) and updating the item. Not sure how the value became null in the first place.
