Hi Kristiyan, sorry for not being clear. I tried the metabase repository with the Guix and the Nix package. The Nix package works, but the one from Guix not. I also just tried the clojure-guix-broken repo now (I haven't seen this yesterday) with the Guix package, and it didn't find the class. Unfortunatly, I have no idea why the class files are not being found. After seeing all those: Warning: failed to load the S3TransporterFactory class I thought it might be related. But maybe not. I hope you find the issue. Roman Kristiyan Kanchev writes: > Hello Roman, > > What do you mean that you're getting the same error? Getting the same > error with Guix Clojure or with Nix Clojure?
