An Azure communication platform for deploying applications across devices and platforms.
@Gabriel Duchateau It seems that the api-version '2021-10-15-preview' is not supported for creating a System Topic for your Event Subscription.
You can try updating the api-version to one of the supported versions mentioned above. If you are using the Azure portal, you can select the supported version from the dropdown list. If you are using Azure CLI, you can specify the api-version in the command using the --api-version parameter.
For example, to create a System Topic with api-version '2023-07-01', you can use the following Azure CLI command:
az eventgrid system-topic create --name <system-topic-name> --resource-group <resource-group-name> --location <location> --sku <sku-name> --api-version 2023-07-01
Replace <system-topic-name>, <resource-group-name>, <location>, and <sku-name> with your own values.
