Was this previously working? what does your recipe code look like?

[mccw]

I just tested this in development and it looks like it's working. So this might be due to the fact that the server in question was deleted this morning and re-created, so it's probably client/vault related.

[mccw]

Yes, it does look like it had something to do with vault permissions. I'm closing this as a non-issue. thank you for the quick response!
