Hi @MobileTen. Thanks for your comment. I'm not sure what you mean by "rewrite" the tree rather than "replace" it, though. In your linked video, one thing Alex does differently is initialize DeclSyntax nodes using explicit initializers rather than using plain strings. I haven't noticed a difference, though. When I replace return ["case bar(Bool)"] with return [DeclSyntax(try EnumCaseDeclSyntax("case bar(Int)"))], I continue to see the same issue. Can you elaborate on what I'm doing incorrectly?

We're still experiencing this issue in Sandbox. We're POSTing to https://sandbox.itunes.apple.com/verifyReceipt and we consistently get 21002. Production seems okay.
