Swagger doesn't like <requestFiltering removeServerHeader="true" /> in web.config

I had the line in the wrong section. New web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>

  <!-- To customize the asp.net core module uncomment and edit the following section.

  <system.webServer>
    <directoryBrowse enabled="false" />
    <security>
      <requestFiltering removeServerHeader="true" />
    </security>
    <httpProtocol>
      <customHeaders>
        <add name="X-Content-Type-Options" value="nosniff" />
        <remove name="X-Powered-By" />
      </customHeaders>
    </httpProtocol>
  </system.webServer>

</configuration>
