请求协助排查Python脚本中sys.argv输出错误问题

Hey there! Let's break down why you're hitting that error with sys.argv[1] and get it fixed.

The Root Cause #

That error (almost certainly an IndexError: list index out of range) happens because you aren't passing enough command-line arguments when running your script. The sys.argv list only contains the path to your script itself at index 0 if no extra arguments are provided—so trying to access index 1 doesn't exist, hence the crash.

Fixes to Try #

• Pass the required argument when launching the script
  Instead of running just python ./test.py, include the addon handle value as a parameter. For example:

  python ./test.py 789
  

  Here, 789 will be captured as sys.argv[1], which your code can safely convert to an integer.

• Add input validation to prevent unexpected crashes
  It's smart to add a check to make sure the argument exists before using it. Update your script near the top with this logic:

  import sys
  
  # Check if the addon handle argument was provided
  if len(sys.argv) < 2:
      print("Oops! You need to provide an addon handle as a command-line argument.")
      print("Usage: python ./test.py <addon_handle_integer>")
      sys.exit(1)  # Exit with an error code to signal a problem
  
  # Now safely convert the argument
  addon_handle = int(sys.argv[1])
  

  This way, if someone runs the script without the required argument, they get a clear, helpful message instead of a messy traceback.

A Quick Note on Your build_url Function #

I noticed you're using sys.argv[0] to construct a URL. Just keep in mind that sys.argv[0] is the full or relative path to your script (depending on how you launched it). If this URL is meant to be used in another context, double-check that the path makes sense for where the URL will be accessed—but this isn't related to your current error, just a little heads-up!
