Cant package project please help

EDIT: Solved !! Deleted like 3 unhooked nodes in one of my animBPs, apparently the packager thing HATES that

Hi I am unable to package my UE5 EA2 project for Windows using Unreal Frontend, for some reason it keeps failing, but it packaged fine yesterday. The only change I made was editing a widget blueprint, which I tried deleting and also clearing of any code, but it doesn’t make a difference.

I have this huge block of errors repeated twice in the log every time. Build settings are By the book, do not deploy, single pak file, tried development and also shipping.

Any help very appreciated thanks

Could your project be referencing a function in the blueprint you edited/deleted, hence the unknown function error

Hi thanks for reply, I think that might be possible, I tried opening and saving any blueprint that I changed between the time it did package and the time it didn’t and it did not fix the problem. I also tried validating all content folders, and I rebuilt all levels. Is there any way to tell which blueprint might be causing the error? Also I edited the post with the full error, when I originally copy and pasted it, I didn’t get it all for some reason.

Thanks

I saw someone else have the same issue recently, based on your log files. Take a look at this issue and see if the solution helps

Thanks so much ! I went through every animBP in my project and only one had literally like 3 unhooked nodes, apparently the packager must hate that because I deleted them and now packaged with frontend with no errors. Thank you !!
