Event Grid sys topic subscription

[hichamveo]

I'm trying to create with az cli an Event grid system topic subscription but it fails with the foloowing error:

"statusMessage": "{"status":"Failed","error":{"code":"ResourceOperationFailure",
"message":"The resource operation completed with terminal provisioning state 'Failed'.","details":[{"code":"Url validation",
"message":"Webhook validation handshake failed for https://mylogicapp.azurewebsites.net/runtime/webhooks/workflow/scaleUnits/prod-00/workflows/84aa5895b4324710853436be49fed029/triggers/When_a_resource_event_occurs/paths/invoke.

$ResourceGroupName = 'myrg'
Set-AzContext -Subscription $subscription

az eventgrid system-topic event-subscription create --name 'testsub' -g $ResourceGroupName --system-topic-name my-systopic

but when I create the subscription manualy via Azure portal it works fine. I suspects the validation handshake via powershell is not taken care of url queries and stops at "Invoke"

For minformation my workflow test has a logic to validate the handshake to retun validation code.

any help please?

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @jfggdl.

for information, the creation works fine using the rest API :

https://docs.microsoft.com/en-us/rest/api/eventgrid/version2021-06-01-preview/system-topic-event-subscriptions/create-or-update#webhookeventsubscriptiondestination

the endpoint url is regestered with url queries

@hichamveo Apologies for the late reply. For webhook endpoint type, this should be the corresponding webhook URL. I am sending the below sample command which has the example of the webhook URL:

az eventgrid system-topic event-subscription create --name NewFileCallRunbook -g EventGrid --system-topic-name NewFileAtStrg --endpoint-type webhook --endpoint https://e53cc45XXXXXXX777bdb5e.webhook.we.azure-automation.net/webhooks?token=N4hV1C0XXXXXXXXXXXX11gs%3d --subject-begins-with /blobServices/default/containers/cont1/blobs/folder1/ --subject-ends-with .txt --subject-case-sensitive false --included-event-types Microsoft.Storage.BlobCreated

Please change your --endpoint to the webhook url in your command and run the command again. Awaiting your reply.
