Unexpected content validation errors

[d-swift]

Hey, content validation is throwing a strange error and not returning any validation issues.

Here is the output:

Hey @d-swift, can you update to the release candidate for the next version of Spectacles and try again?

pip install spectacles==2.3.0rc3

[joshtemple]

I believe this is a duplicate of #610.

[d-swift]

Thanks, I'll try this!

Thanks @d-swift! Looks like we can't always rely on those content objects having a title. I wish we had better guarantees from the Looker API about this sort of thing, but we don't.

I'll get a fix written for this as soon as possible. If it's something you need sooner, I'd also definitely accept a PR! It should be a quick fix to use .get('title') instead of ['title']

Closing as duplicate.
