invalid token not caught

[kjappelbaum]

it seems that the is_connected check is not good enough

[kjappelbaum]

to be checked with a unit test on the cheminfo-py side since

aiidalab-eln/aiidalab_eln/cheminfo/__init__.py

Lines 103 to 110 in a1340f5

	def is_connected(self):
	if (
	self.session
	and self.session.is_valid_token
	and self.session.has_rights(rights=["read", "write", "addAttachment"])
	):
	return True
	return False

looks reasonable
