Hi, I don't think you've explained the issue in enough detail to confirm a bug in Django. Please reopen the ticket if you can debug your issue and provide details about why and where Django is at fault. At first glance, it looks like an issue in netmiko. If you're having trouble understanding how Django works, see TicketClosingReasons/UseSupportChannels for ways to get help.

This is analyzed in more detail and determined "invalid" in #35085.
