Error while extracting Fortnite .pak file

[VideoGamePlayer7]

Hello! I was trying to extract a .pak file of Fortnite, but an error occured:

Error: incomplete input file -10:
Can't read 8 bytes from offset 00000000004e1f40.
Anyway don't worry, it's possible that the BMS script has been written
to exit in this way if it's reached the end of the archive so check it
or contact its author or verify that all the files have been extracted.
Please check the following coverage information to know if it's ok.

coverage file -10 100% 5119808 5119808 . offset 00000000004e1f40

Last script line before the error or that produced the error:
130 get CHUNK_END_OFFSET longlong TOC_FILE

Can someone help me? Thanks!

I have tried using the normal QuickBMS and QuickBMS for 4 GB files, and I also tried running as administrator, and it didn't seem to work. I have tried using a key to get the extracted files.

I guess you selected a non-pak file or a wrong key.
