For some reason I can't get favicon to show in my app

[vmlstandard]

Description

This code demonstrates the problem with favicon:

from nicegui import app, ui

favicon_name = "favicon3.ico"
app.add_static_files('/static', 'static')

@ui.page('/', favicon='static/' + favicon_name)
def index_page() -> None:
    # ui.html("<link rel='icon' type='image/x-icon' href='static/" + favicon_name + "'>")
    ui.avatar('img:/static/' + favicon_name, color='white', square=False)

ui.run(title='FavIcon Demo', favicon='static/' + favicon_name)

static.zip

It only works with the ui.html(...) line un-commented.
The @ui.page and ui.run seem to ignore the favicon

I have added several favicon files I have tried, in case these could be the issue.

I'm probably missing something...

Please help solving this mystery,

Thank you

Are you absolutely sure that there is a static folder containing your favicon in the working directory?

Btw: this is the code which determines the favicon url

nicegui/nicegui/favicon.py

Lines 26 to 44 in 9c7a40e

	def get_favicon_url(page: page, prefix: str) -> str:
	"""Return the URL of the favicon for a given page."""
	favicon = page.favicon or core.app.config.favicon
	if not favicon:
	return f'{prefix}/_nicegui/{__version__}/static/favicon.ico'
	favicon = str(favicon).strip()
	if _is_remote_url(favicon):
	return favicon
	if _is_data_url(favicon):
	return favicon
	if _is_svg(favicon):
	return _svg_to_data_url(favicon)
	if _is_char(favicon):
	return _svg_to_data_url(_char_to_svg(favicon))
	if page.path == '/' or page.favicon is None:
	return f'{prefix}/favicon.ico'
	return f'{prefix}{page.path}/favicon.ico'

So you either need to provide the full remote url or use the file location.

ui.run(favicon='rocketicon.png', uvicorn_logging_level="debug")
but the result html still keep

what wrong with my env or code? thank you
