Trouble with anvil.js.window : 'anvil.js' is not a package

Anvil Q&A

So it looks like RSAKPI is a client side module containing the RSAKPI Form class.
You are importing Transport from the RSKAKPI module.
This is what is breaking on the server.

When you load the RSAKPI module on the server
the server tries to do from anvil.js.window import navigator
But the window object doesn’t exist on the server.
The window object is the browser javascript namespace.

You have a few options.

  • Move Transport somewhere else, likely an isolated client module that doesn’t need the anvil.js.window object.
  • Don’t import navigator directly, instead import anvil.js and replace navigator.clipboard with anvil.js.window.navigator.clipboard
  • do a server side check and only import navigator if you’re not on the server
from anvil import is_server_side
if not is_server_side():
    from anvil.js.window import navigator

I would probably go with the first or third option.
