New tab in browser don't show with python webbrowser

Question

Hello,

I have to display a PDF document coming from blob storage in a new browser tab. It works great locally but once successfully deployed on Azure App Services the Webapp functions but the new tab never shows up.

• I am using Python 3.8 on an Azure Linux Web App
• To open new tab I use webbrowser.open_new_tab(url)
• The SAS Token is OK to pull file from blob storage but I get 204
• In container logs I can see that all operations are OK, I can even Ctrl+Click the file URL to have it displayed in new tab:

I am really stuck on that one. I it a permission issue or shall I use another way in Python to open the tab?

Thanks for any help.
