  • SystemLink Server

Issue Details

  • When I try to upload a package built in G Web Development Software to SystemLink Cloud, I get the following error:
Failed to upload!
Invalid .nipkg file: No index page found: Index.htm, Index.html, Main.htm, Main.html, Function.htm, Function.html
  • I am trying to load a Package created in G Web Development Software to SystemLink Server and I am getting an error:
The .nipkg file is not valid


One of the possible reasons for facing this error is having an invalid name for the top-level VI in the Web Application Project. Ensure that the name of the top-level VI is set to one of the following:
  • Main.html
  • Index.html
  • Function.html
