Issues with apt-s3 during sudo apt update

[33base]

Hello everyone,

I've been trying to use apt-s3 to set up an S3 bucket as an APT repository. I've followed the documentation and set everything up correctly, but I'm running into an issue when I run sudo apt update. Here's the error I'm getting:
Reading package lists... Done
E: Method s3 has died unexpectedly!
E: Sub-process s3 returned an error code (1)
apt-s3 version: 0.1.5 (Go version: go1.17.6)

Some details about my setup:
OS: Ubuntu Focal
I've confirmed that my AWS credentials are correctly set up, as I can download files directly using apt-s3 -download.
Interestingly, when I use the -download option with apt-s3, it works perfectly and I can fetch files from my S3 bucket. However, the sudo apt update command consistently fails.

Has anyone else encountered this issue or have any suggestions on how to debug or resolve it? Any help would be greatly appreciated!

Thank you in advance!
