Since upgrading to 0.48, several of our developers running linux are running into the following error when starting up the app:

ERROR -- ddtrace: [ddtrace] (/home/mscrivo/affinity/vendor/bundle/ruby/3.0.0/gems/ddtrace-0.48.0/lib/ddtrace/runtime/container.rb:71:in `rescue in block in descriptor') Error while parsing container info. Cause: undefined method `[]' for nil:NilClass Location: /home/mscrivo/affinity/vendor/bundle/ruby/3.0.0/gems/ddtrace-0.48.0/lib/ddtrace/runtime/container.rb:56:in `block (2 levels) in descriptor'

Even if tracing is disabled. Note, they are running the code on VMs, but not containers. Downgrading to 0.47 gets rid of the error. People using macOS don't see this.

Ruby version: 3.0
