this is a small snippet of code in which the type solver does not recognize type aliases inside the createPrinterDataRowEntry type function, assert(markups, "type alias markups not found") here throws

place file which contains a reproduction:
bug_reproduction.rbxl (67.6 KB)
the issue occurs inside ReplicatedStorage/Types

Expected behavior

Markups, and other type aliases should be accessible from within createPrinterDataRowEntry
