there is a bug in the system which prevent adding event into dashboard

def get_notification_config():
return {
“for_doctype”: {
“Error Log”: {“seen”: 0},
“Communication”: {“status”: “Open”, “communication_type”: “Communication”},
“ToDo”: “frappe.core.notifications.get_things_todo”,
“Event”: “frappe.core.notifications.get_todays_events”,
“Error Snapshot”: {“seen”: 0, “parent_error_snapshot”: None},
“Workflow Action”: {“status”: ‘Open’}
“for_other”: {
“Likes”: “frappe.core.notifications.get_unseen_likes”,
“Email”: “frappe.core.notifications.get_unread_emails”,
“for_module”: {
“Social”: “”

the code extracted as above from methon get_notification_config, for doctype event a function other than a dict as filtering condition is returned, actually the function is relevant for the calendar view of event doctype itself, for embed event in other doctype’s dashboard, this function is irrelevant, so after changed the relevant code in as below

	if filters:
		# get the fieldname for the current document
		# we only need open documents related to the current document
		if isinstance(filters, dict):
			filters[fieldname] = name
			filters = None
		total = len(frappe.get_all(d, fields='name',
			filters=filters, limit=100, distinct=True, ignore_ifnull=True))
		data['open_count'] = total
