Hi, I am getting following issue. Can you advice me is this bug issue in my way of using mount-s3? I am mounting directory bucket. It seems to be supported.

Hi @JakubMartinovicHusar, yes, the latest version of mountpoint should work with directory buckets. Could you give us a bit more information on the version you were using? Is it an official release or it is built from source?

Hi Monthon, I have used following command to install mountpoint. So official version. I am currently using version 1.3.2. wget https://s3.amazonaws.com/mountpoint-s3-release/latest/x86_64/mount-s3.deb sudo apt-get install -y ./mount-s3.deb Regards, Jakub

Hi Jakub, I was able to reproduce this problem when I don't have a valid IAM credentials to access the directory bucket. You will need to use an IAM role with s3express:CreateSession permission for your directory buckets in order to access them. You can see an example in our configuration document (https://github.com/awslabs/mountpoint-s3/blob/main/doc/CONFIGURATION.md#iam-permissions).

Anyway, the reported error doesn't tell us anything about permission at all. I think we should improve that error message. Let me know if this solve your problem and I will create another thread for the log improvement.
