Unable to view eventgrid subscriptions in the azure portal. Unable to create new ones too - azure-eventgrid

Question

I have around 12 eventgrid subscriptions already created for topic type 'Azure subscription'. Unable to see any of them in Azure portal since 30th May 2018.
I could see the list in azure cli (refer screenshot list_shown_in_cli)
but could not see the same in GUI (refer screenshot list_not_shown_in_gui).
Moreover, I am unable to create new subscriptions too. I observed the javascript error in browser's developer console when attempted to create new eventgrid subscription (refer screenshot error_creating_eventgrid_subscription).

Answer 2

It looks like your error is invalidRG - are you sure the resource group and or resource your are trying to subscribe to are valid?
It may also be an invalid resource type that you are trying to listen to. Things like Container Registry are not yet supported. The full list of supported sources can be found here: https://learn.microsoft.com/en-us/azure/event-grid/event-sources
A good first test to ensure your subscriptions are still available and valid would be so search for them via AZ CLI 2.0
. You can open it in the CloudShell or download to your local client and then run az eventgrid event-subscription list.
