Unable to save slice changes

Hey, Phil! Thanks for the tip about the pull command being deprecated.

I'm wondering if this is related to my team's inability to save slice changes now. I realize that our repositories didn't start off through SliceMachine, so I'm guessing it's possible there's some sort of incompatibility now.

Specifically for our repositories, we get the following message with a 500:

Something wrong happened while updating the custom type article

And we also have a failed request to https://silo2hqf53.execute-api.us-east-1.amazonaws.com/prod/customtypes for both repositories when we try to create new slices.

Would you mind taking a look at what's going on? Thank you!
