I am getting the error for event based trigger as
Operation on target ####@@@#### failed: The Microsoft.EventGrid resource provider is not registered in subscription $$$@@@@###. To resolve this, register the provider in the subscription
and retry the operation.
Please raise a new question in ADF forum (the link I have shared), I will answer there.
