Delivery Properties are deleted when enabling DQL on eventgrid subscription

[rachelxj-ms]

Describe the bug

I create a custom topic, create a webhook eventgrid subscription, I added 2 delivery properties.

But when I use az eventgrid event-subscription update to enable DQL on the eventgrid, those delivery properties got deleted.

Related command

az eventgrid event-subscription update --name test2 --source-resource-id "/subscriptions/a77a2c76a66c/resourceGroups/test/providers/Microsoft.EventGrid/topics/topic0927" --deadletter-identity-endpoint "/subscriptions/a77a2c76a66c/resourceGroups/search/providers/Microsoft.Storage/storageAccounts/*/blobServices/default/containers/event-grid" --deadletter-identity systemassigned --endpoint "https://.azurewebsites.net/api/updates"

Errors

delivery properties got deleted.

Hi @rachelxj-ms,

2.55.0 is not the latest Azure CLI(2.64.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.
