title: rdebug-ide with VSCODE returns cannot load such file -- /app/app/rails error
body: <p>I have a dockerized RoR app and I'm trying to run it in debug mode using rdebug-ide and vscode.
  Already added gems ruby-debug-ide and debase.
  I installed ruby extension on vscode and created the launch config:</p>
  <pre><code>&quot;version&quot;: &quot;0.2.0&quot;,
  &quot;configurations&quot;: [
      {
          &quot;name&quot;: &quot;Attach to Docker&quot;,
          &quot;type&quot;: &quot;Ruby&quot;,
          &quot;request&quot;: &quot;attach&quot;,
          &quot;remoteHost&quot;: &quot;0.0.0.0&quot;,
          &quot;remotePort&quot;: &quot;9000&quot;,
          &quot;remoteWorkspaceRoot&quot;: &quot;/app&quot;,
          &quot;cwd&quot;: &quot;${workspaceRoot}&quot;,
          &quot;showDebuggerOutput&quot;: true,
      }
  ]
  </code></pre>
  <p>On docker-compose.override I added the command:</p>
  <pre><code>command: bundle exec rdebug-ide --debug --host 0.0.0.0 --port 9000 -- rails s --host 0.0.0.0 -p 3000
  </code></pre>
  <p>When I run <code>docker-compose up backend</code> I can see the debug server running:</p>
  <pre><code>Fast Debugger (ruby-debug-ide 0.7.2, debase 0.2.4.1, file filtering is supported) listens on 0.0.0.0:9000
  </code></pre>
  <p>The problem happens when I start the debug task on VSCODE. I get this error:</p>
  <pre><code>Uncaught exception: cannot load such file -- /app/rails
  </code></pre>
  <p>The entry point and workdir on Dockerfile:</p>
  <pre><code>WORKDIR /app
  ENTRYPOINT [&quot;bundle&quot;, &quot;exec&quot;]
  CMD [&quot;rails&quot;, &quot;server&quot;, &quot;--binding=0.0.0.0&quot;]
  </code></pre>
  <p>If I run the app normally with <code>docker-compose up backend</code> and do <code>docker container ls</code> I can see the start command:</p>
  <pre><code>bundle exec rails server --binding=0.0.0.0
  </code></pre>
