Visual Studio Team Services Deployments error

I created 4 tenants within the last week and configured the Visual Studio Team Services Deployments extension on each.
On 2 of them everything works fine, but on the other 2 I get this error every time I try to deploy even though everything appears to be configured correctly in the extension settings and in the Azure Devops webhook.

Schema validation failed loading [
“keyword”: “required”,
“dataPath”: “.hooks[0]”,
“schemaPath”: “#/properties/hooks/items/required”,
“params”: {
“missingProperty”: “name”
“message”: “should have required property ‘name’”

Good morning,

Could you try removing the hooks file? Or could you try adding names or changing the existing names in those files?

Thanks in advance!
