I'm following the instructions here to add a --deadletter-endpoint to an existing EventGrid subscription.
The process is failing with error: Event subscription doesn't exist.
What am I missing?:
containername=eg-dead-letter-events //container where deadlettered events will be stored
topicid=$(az eventgrid system-topic show --name egtop-dev -g TEST_DEV --query id --output tsv) //name of eventgrid system topic
storageid=$(az storage account show --name stgdev --resource-group TEST_DEV --query id --output tsv) //name of storage account where deadlettered events will be stored
az eventgrid event-subscription update \
--name egsub-dev \ //name of Event Subscription here? also tried System Topic name, no go.
--source-resource-id $topicid \ //I cannot find a clear reference for what is supposed to go here
--deadletter-endpoint $storageid/blobServices/default/containers/$containername
Event subscription doesn't exist.Edit 1: Made some progress
az eventgrid event-subscription list --topic-type "Microsoft.Storage.StorageAccounts" --location southcentralus
az eventgrid event-subscription update --name egsub-dev --source-resource-id /subscriptions/$subscription/resourceGroups/$resourceGroup/providers/Microsoft.Storage/storageAccounts/storageAccountThatTriggersEventGrid/providers/Microsoft.EventGrid/eventSubscriptions/egsub-dev --deadletter-endpoint $storageid/blobServices/default/containers/$containername

Thoughts on this one?
Regarding the issue, please update the script as below
sourceid=$(az eventgrid system-topic show --name egtop-dev -g TEST_DEV --query source --output tsv)
storageid=$(az storage account show --name stgdev --resource-group TEST_DEV --query id --output tsv)
az eventgrid event-subscription update \
--name egsub-dev \
--source-resource-id $sourceid\
--deadletter-endpoint $storageid/blobServices/default/containers/$containername
