Uploading dSYM not found after succeessful upload

On-Premise

We’re using a self-hosted sentry instance and we use it to report issues on a native iOS project
some of these reports come with redacted reports and not showing anything useful
so I tried to upload the dSYM files through Fastlane by using the following lane

lane :upload_symbols do
      download_dsyms(min_version: "MINIMUM_VERSION")
      ENV["SENTRY_URL"] = "SELF_HOSTED_URL"
      sentry_upload_dsym(
        auth_token: 'AUTH_TOKEN',
        org_slug: 'ORG_SLUG',
        project_slug: 'PROJECT_SLUG',
      )
      clean_build_artifacts
    end

it uploads successfully but when I go to Project>Settings>Debug Files I can’t see the files there
