Possibly unescaped error: S3 object '%s' does not exist

[cep21]

Describe the bug

I'm using nix and an S3 bucket I don't have read permissions to. I see this error in the logs

       error: s3://company/object.whl

       response body:

       S3 object '%s' does not exist

My guess is that nix intends it to not literally print %s, but instead is trying to do some printf formatting.

nix --version
nix (Nix) 2.24.10

Steps To Reproduce

I was trying to run a nix build. Sorry there aren't complete steps to reproduce but I hope the error is clear?

Expected behavior

You likely wanted to print something like this

       S3 object '<some-name>' does not exist
