Static files in allowlist ignored

[gioxc88]

I am using v 0.5.8

I am trying to serve a static file in my notebooks directory by using the following syntax

voila . --VoilaConfiguration.file_allowlist 'myfile.xlsx'

But it's not working
Is this a known issue?

I thought I should now be able to see myfile.xlsx in the browser

I am experiencing similar issue, but not just one static file. It seems any changes to the file_allowlist traitlet is ignored. I can trace the problem to load_config_file which can return an empty Config and thus overrides any supplied traitlets :

voila/voila/server_extension.py

Lines 56 to 83 in 14d44a1

	def load_config_file() -> Config:
	"""
	Loads voila.json and voila.py config file from current working
	directory and other Jupyter paths
	"""
	new_config = Config()
	base_file_name = "voila"
	config_file_paths = [*jupyter_config_path(), os.getcwd()]
	for current in config_file_paths:
	py_loader = PyFileConfigLoader(filename=f"{base_file_name}.py", path=current)
	try:
	py_config = py_loader.load_config()
	new_config.merge(py_config)
	except ConfigFileNotFound:
	pass
	json_loader = JSONFileConfigLoader(
	filename=f"{base_file_name}.json", path=current
	)
	try:
	json_config = json_loader.load_config()
	new_config.merge(json_config)
	except ConfigFileNotFound:
	pass
	return new_config

If I change this line:

voila/voila/server_extension.py

Lines 90 to 92 in 14d44a1

	voila_configuration = VoilaConfiguration(
	parent=server_app, config=load_config_file()
	)

to voila_configuration = VoilaConfiguration(parent=server_app) then the supplied traitlets are used.
