Summary:
When creating a web deployment a popup error appears with the following text:

Error in NextDeploy(). : 'null' is null or not an object



What is the cause of this error?

Solution:
This occurs when the deployment is taking a long time to complete and a timeout configured within the Web Server has expired. If necessary you can increase this timeout as follows.

  1. In the Web Server installation folder (the default location of which depends on the product version) locate the file postxml.asp
  2. Open the file in Notepad
  3. Adjust the Server.ScriptTimeout to greater than its default of 300 seconds and edit the comment above it accordingly (eg double the timeout to 600 seconds or 10 minutes).
  4. Save and close the file.
