BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@booklet{EasyChair:12378,
author = {Julia Anderson and Robert Jhon},
title = {Supply Chain Integration: Enhancing Collaboration for Competitive Advantage},
howpublished = {EasyChair Preprint 12378},
year = {EasyChair, 2024}}
