Hi @ayush91985 , your post was closed here since it is a duplicate of this post.
As @hrishikesh highlighted your error, you are importing your pdf wrongly. To fix it, navigate to your file at /src/components/Resume/ResumeNew.js and then change your pdf import to the below
import pdf from "../../Assets/Soumyajit_Behera-BIT_MESRA.pdf";
Secondly change your Build command to the below
CI=false npm run build
Make the changes and then redeploy.
Let us know the outcome.
Thanks.
