title: Dynamic Script Block - Java Runtime Error - Webforms
body: <p>I have an old WebForms app that I'm working on.  I'm running in debug mode. </p>
  
  <p>I get an error message when loading a page.  It is a message from a dynamic script:  </p>
  
  <p>Javascript Runtime Error "False" is undefined</p>
  
  <p>I'm stuck as to how to debug this.  I was thinking that I might need to update a nuget package, but I don't know which one.  </p>
  
  <p><strong>Update:</strong></p>
  
  <p>Get this error with IE 11.  Do not get the error with Chrome.  </p>
