When testing my project on 4.10 Preview 4 I was unable to package the project. After reopening the editor Output Log was filled with compiler errors and warnings, which was strange, because all BPs in the project compiles and PIE works as a charm (or so it seems). The log shows the same problems with every opening of the editor and packaging always fails.
It turned out that the wildcard array type input I use in some macros is to blame. I recreated the issue quite easily and here is a test project:
Did this make it to the 4.10 release (launcher version)? Because I’m attempting to package and I’m receiving “Error: [compiler UI_Dialogue] Error The type of Item is undetermined. Connect something to GetOption to imply a specific type.” when trying to Cook for Windows or Package.
You are correct that the issue still seems to be occurring in the 4.10 launcher version. After checking in 4.10, I checked the status of this issue, and it has been resolved internally. The solution will be available in a later version.
