Basic authentication with local login template file returns html error 405

Panel
,
1

Following the docs:

  1. Downloaded the default login template to a local file called ‘basic_login.html’
  2. Served the app with
    panel serve app.py --basic-auth my_password --cookie-secret my_super_safe_cookie_secret --basic-login-template basic_login.html

The login page loads, but once the username and password are provided, it returns a page with “405: Method Not Allowed”.

Any ideas on how to fix this? I was hoping to be able to use a custom login template.

Thanks.

pn.extension(template="fast")

logout = pn.widgets.Button(name="Log out")
logout.js_on_click(code="""window.location.href = './logout'""")
pn.Column(f"Congrats `{pn.state.user}`. You got access!", logout).servable()

Hi Marc,
Thanks for your prompt response. Unfotunately, your ‘script.html’ has become mangled by the formatting. Is there a way to upload it as text?

Here’s script.html

Thanks. Turns out it was a problem with my panel version. The html error occurs with versions 1.4.1 and 1.4.5. Upgrading the version to 1.7.1 resolves the issue.
