unhandled exception when packing mod

[Paytonpay]

Im getting an unhandled exception error when attempting to pack a mod:

Unhandled exception. Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'CUE4Parse.UE4.Pak.Objects.FPakEntry' does not contain a definition for 'ChunkId'

Game is Abiotic Factor running on ue5_5
The fmodel export folder path is unchanged from the original

Any ideas on whats going wrong? : (

Your game probably needs custom CUE4Parse lib support
Contact FModel to confirm its support
I will update the library next week to see if it will be fixed or not.
Meanwhile, you can upload one of the original utoc/ucas files for faster help

Please upload the files that you wanna pack

Hi! I have the same issue, but with Lollipop Chainsaw. I've uploaded utoc w/o ucas, cause ucas is 13gb. Can upload if you need it.

These?

Perhaps the error can be circumvented by checking if there is a record for the modified file in the .utoc file at all. Perhaps it is stored in a pak file and does not need to be packaged in .ucas.

I had a similar problem with the Game.locmeta file. I got around it by fixing the line from:
var filedata = provider.Files.Values.Where(a => a.Path.Equals(filename, StringComparison.CurrentCultureIgnoreCase));
to:
var filedata = provider.Files.Values.Where(a => Path.GetExtension(((AbstractVfsReader)((VfsEntry)a).Vfs).Name) == ".utoc" && a.Path.Equals(filename, StringComparison.CurrentCultureIgnoreCase));

And the necessary file and the other one, which was not there at all, I packed into a regular pak-file using the UnrealPak.exe utility from the UE4 package of the corresponding version, replacing the one created by this utility.
